Yet another 2.6.35 regression (AGP)? (resend)

I have found one system, where 2.6.35 does not work (as tested with rc3 and rc4)
That Intel system has no problems in 2.6.33.x nor 2.6.34.0.

The problem seems to be in AGP - I can boot if I specify "agp=off" - but of course only in text mode...
There seems to be a hard lock-up, so the only way to show the crash is by picture 8-)

Since I do not build kernel on that machine, I did not do any bisect tests, however if someone is interested in digging deeper, I can try... Preferably a patch to try out ;-)

This bug seems to be different then https://bugzilla.kernel.org/show_bug.cgi?id=16179

Should it be blamed on BIOS (the conflict indicated just before the crash)?

Thanks, Woody

PS. Resending, as original post cc'd drivers_video-dri-intel@xxxxxxxxxxxxxxxxxxxx, what seems to be bad...
