more mtrr/pat issues x86_64 4gb ram

[gjohnson5]

I've been trying the rawhide kernels since PAT is now an option when
configuring the kernel, but on my desktop the mtrr are not configured
correctly assuming by the bios and disabling them makes system performance
drop to unusable levels.  PAT hasn't function as of
kernel-2.6.26-0.43.rc4.git2.fc10


ASUS NCT-D ---> 1009001 bios
