T40 - new install |

Good day,
I've installed (several times) on a ThinkPad T-40, trying both manual kernel config and genkernel. I followed the online manual explicitly (I think). The machine is currently loaded with the manual config. Either way, the results are similar.
Grub shows the two boot options, then begins loading the OS.
The machine begins to boot, starts loading modules, then kernel panics:
VFS:Cannot open root device "hda3" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
There is a single fixed disk:
Device Boot ; Size ; System Filesystem ; Mount point
======= ==== ; ===== ========= ========= ; =========
; /dev/hda1 ; * 32M Linux ; ; ext2 ; ; /boot
/dev/hda2 ; ; 3G Linux swap ; none ; ; none
/dev/hda3 ; ; ~71G Linux ; ; ext3 ; ; /
I am able to mount and use these partitions after booting from CD. /etc/fstab (/mnt/gentoo/etc/fstab when booted from disk) looks good.
Filesystems ext2 and ext3 are compiled into the kernel.
Grub details:
device.map
(hd0) ; /dev/hda
grub.conf
; default 0
; timeout 5
; splashimage=(hd0,0)/boot/grub/spash.xpm.gz
title=Gentoo Linux 2.6.17-r8
; root (hd0,0)
; kernel /boot/kernel-2.6.17-gentoo-r8 root=/dev/hda3
; title=Gentoo Linux 2.6.17-r8 (rescue)
; root(hd0,0)
kernel /boot/kernel-
2.6.17-gentoo-r8 root=/dev/hda3 init=/bin/bb
I used grub-install /dev/hda with no errors. I've played around with the "root=" entry, but to no avail - not sure I'm understanding this one...
The kernel image appears to be valid, with no typos in filename/grub entries.
Any ideas? Seems that the kernel begins to load, but can't mount the root filesystem?
Thank-you for any pointers.
