I do not find that in .config at all, set or not:

:; grep X86_PAT /usr/src/linux-2.6/.config

returns nothing.

But the kernel which dies does generate this:

Apr 24 04:28:09 [kernel] [ 0.000000] x86: PAT support disabled.

X86PAT was enabled in 2.6.26-rc1, the problem is when loading fglrx
there is a conflict, you have to disable X86pat for fglrx PAT to be
enabled.

Has the problem been fixed in 2.6.26-rc1 or in the current -git?

I plan on giving current master a test tonight.

Cool;
From what I've experienced out of 2.6.25-rc* to the latest git with a
macbook pro; 2.6.25-rc7,8,or 9 runs the best i.g.
not as hot, fans don't trip as often, when listening to music, and
then compiling you don't have a skip., suspend works
lircd works, isight works. As for 2.6.26-rc1 lircd doesnt work for
some reason, isight now works, atheros now works, fglrx does'nt due to
something deep into the kernel was changed(who knows what that might be)
did find the kernel running kind of quieter but noticed the fans
would rev up every so often (estimation would be around 35 min to 60
min + or - )
probably a new mechanism to cool things down. Sound is working, but
every so often a song sounds as if you have blown out speakers.
I probably will pull the latest git, but after spending countless
hours, trying to get fglrx up and running, and realizing something
was drastically changed in that area, I've decided to go get some
liquid propulsion and call it a day.

Git master as of 3de2403e allows me to run X again.

After installing the new kernel I also re-compiled all of the X server
stack (libdrm, libpciaccess, mesa, the X server and the video driver).
I don't know how much of a difference that made.

I don't know whether the problem was sched, x86, agp or dri related,
but AFAICT it is now fixed.

Thanks,

Well; After reverting to 2.6.25-rc* then contemplating(beer) for a
while I decided to pull the latest git today, the problem now was with
atapiix, So with that in mind I decided to load 2.6.26-rc1 everything
seems to be O.K., the problem I have is: I receive a blank screen when
I load fglrx,
then startx. I think it has to do with /proc/mtrr and pat almost as if
I'm on the wrong screen. With that said I wouldn't be such a pain
about wanting fglrx, hell I don't even play video games, well a long
time ago at least(Myst, Riven, schism)or use 3D applications, but this
module was the only module that was at least working with the suspend
mechanism, This way I can test X11 and see if appletouch can survive,
scroll function on the mighty mouse can survive,and DVD playback can
survive properly after a wake-up. With that in mind has anybody gotten
suspend to work with radeonhd, or any other module for the macbook
pro. That way I can at least have that function working,and out of the
way, so I can move on to other things, besides having my eyes go
crosseyed trying to find code that isn't there.
Anyways I'll let you know if I come upon anything interesting;
regards;
