Weird report.
You might try booting with DRM debugging turned on and looking at
dmesg to see what's going on. I presume that you have a second machine
that you can shell in on.
To turn on debug in grub.conf do something like this, of course
dropping the modeset part if you don't need it:
title 2.6.32-gentoo-r2 MS=3D1, DRM=3D0x06
root (hd0,6)
kernel (hd0,6)/boot/bzImage-2.6.32-gentoo-r2 root=3D/dev/sda2
i915.modeset=3D1 drm.debug=3D0x06
This will create a lot of output in dmesg so you may not want to run
with it long term, but it's helped me find a few things over the last
couple of weeks.
Hope this helps,
Mark
