Yes, after giving up on an issue of Debians make-kpkg with Kernel 2.6.35 "+"
sign in version number[1], I used make deb-pkg to compile
2.6.35-rc5-04995-g7441ae8 from TuxOnIce head.

About 5 minutes after booting it, shortly after starting KDE 4 OpenGL
composited desktop session, the machine froze hard. This time I tried accessing
it from another machine, my second ThinkPad, a T23 with SuperSavage chipset.
The frozen T42 did not answer to any ping, "destination host unreachable". Thus
I conclude the kernel was completely locked up. Again it was a fresh boot, no
hibernation cycle in between.

The T23 also has a 2.6.34.1 which didn't yet lock up and has an uptime of 7
days, but only 3 TuxOnIce snapshot cycles. It appears to be stable. Thus I
think it really could have to do with radeon KMS DRM code.
