Ignore the bit about pciaccess and stuff, that's only responsible for 
selecting the correct driver at run time.

it's the actual driver that has a list of pci ids for the cards it supports

what driver are you using?, because i had similar problems like your 
self a couple of months back
i have a radeon 2400XT which works fine with the radeon HD driver

if ctrl-alt-bkspace is working then something is processing the keystrokes
