On thinkpad R52 the i915 does't work any more:

modprobe i915 (delivered from xorg-x11):

[Comment 1 Daniel Drake (RETIRED) 2006-10-09 19:46:30 UTC]

Please reproduce on gentoo-sources-2.6.18

[Comment 2 Daniel Drake (RETIRED) 2006-10-11 19:29:16 UTC]

Actually, testing 2.6.19-rc1 would be a more worthwhile test.
