Hope that you get a more useful response.... FWIW, I Had
precisely these  
symptoms on my Sony 2200 laptop - and can't tell you why -
but it is rock  
sold now. I think there were two things going on:

1. This might be a "kill" switch? Some of my
problems were certainly due  
to the kill switch.  I finally noticed that the little
wireless LEDs were  
off. I had turned them off while using the windows OS -
given that it is  
susceptable to the wonderful new driver attacks - and had
failed to turn  
it on when booting up hardened Linux (which I believe is NOT
susectable to  
the driver buffer overflows).

2. I also suggest a step by step walk-through of the
following page (check  
your kernel config).

P.S. Contrary to their suggestion, I emerged the latest
driver/firmware  
 from portage.

Newbie. (HTH; good luck.)
