updated list of problems I got after upgrading kernel to 2.6

I know such message may be a bit noise to gurus on this
list, but as a
newbie I constantly find searching other people's old post
might help,
so I just write done solution to all problems I have solved,
hoping it
can help the next newbie lurking on this list or coming to
this list by
googling around.

     I. [solved] keyboard doesn't work: solved, need to
adjust keymap
        (thank you for suggested this);
    II. [solved] not able to access /dev/hda, probably new
kernel
        does not recognise on-board IDE controller. Related
kernel
        parameter I configured are:
             I. CONFIG_SUN_PARTITION: y
            II. CONFIG_BLK_DEV_SIIMAGE: y
        ==> solution is to activate CONFIG_BLK_DEV_CMD64X
kernel option

   III. [working on it] parallel port stopped working, it
behave
        like /dev/null (swallow all input to it, no error
message,
        printer no response). /dev/lp0 is not mentioned in
dmesg. I
        remember on 2.4 kernel I use "PC-style Parallel
Port" and it
        works in ECP mode. Related kernel parameter I
configured are:
             I. CONFIG_PARPORT: y
            II. CONFIG_PARPORT_PC: y
           III. CONFIG_PARPORT_PC_FIFO: y
            IV. CONFIG_PARPORT_1284: y
        ==> progress: after re-creating /dev/lp0 node it
works a bit better
            dmesg | head -n 4 > /dev/lp0 would print
something out
            dmesg | head -n 40 > /dev/lp0 would hang the
OS
            my plan: next step is to text various parameter
of parport

    IV. [solved] USB Printer do not work. dmesg shows it
detected
        USB Printer but no device appear in /dev/usb.
Related Kernel
        Parameter:
             I. CONFIG_USB_PRINTER: y
        ==> solution is to run this command as root:
            # mknode /dev/usblp0 c 180 0
            and set cups to use /dev/usblp0 for printer

     V. [working on it] all ALSA sound driver are enabled,
dmesg
        said Sun CS4231 is detected and use irq 10. Try to
play mp3 file
        using madplay, it hangs there after display song
title, no sound
        output, kill -TERM and kill -KILL cannot remove the
dead
        mplayer. Related kernel config:
             I. CONFIG_SND: y
            II. CONFIG_SND_SUN_CS4231: y

        printer no response). /dev/lp0 is not mentioned in

     V. [almost given up] all ALSA sound driver are enabled,
dmesg
        said Sun CS4231 is detected and use irq 10. Try to
play mp3 file
        using madplay, it hangs there after display song

            II. CONFIG_SND_SUN_CS4231: y
        ==> current progress: will try using different
kernel following 
            suggestions on the list or try alsa-driver
package
    VI. [no clue yet] serial port doesn't work. I need
serial port in
        order to manage another headless server with this
machine acting
        as dumb terminal (using minicom).
                dmesg shows no ttyS device. 'MAKEDEV update'
can
                create /dev/ttyS0 and /dev/ttys1 but
accessing these
                devices is not possible:
                        sappho zhangweiwu # cat /dev/ttyS1
                        cat: /dev/ttyS1: No such device or
address
                I have enabled following options in kernel:
                        sappho linux # grep -i serial
.config
                        # CONFIG_SERIAL_NONSTANDARD is not
set
                        # Non-8250 serial port support
                        CONFIG_SERIAL_SUNCORE=y
                        CONFIG_SERIAL_SUNZILOG=y
                        CONFIG_SERIAL_SUNSU=y
                        CONFIG_SERIAL_SUNSAB=m
                        CONFIG_SERIAL_SUNHV=y
                        CONFIG_SERIAL_CORE=y
                        CONFIG_SERIAL_JSM=y
