Comment 2 for bug 489855

Sure thing. I'm attaching two slightly-different X logs (I don't know why the older one is talking about evdev but the newer one isn't). They're both from the amd64 LiveCD. I'd purged PulseAudio at some point and had been restarting X after various changes to see if anything happened; I don't know if both of these are from after nuking PA, but one certainly is, and I can always boot a fresh LiveCD and give you that if you want. The third attachment is lspci -vvnn run as root.

Please let me know if there is any other information you'd find useful, or if there are any further debugging steps I can take. I'm stymied. Thanks!
