Thank you for your letter.
I find it necessary to inform you that problem with mtrr and vesafb
still exists for kernel 2.6.10-rc2. Warning message
"(WW) NV(0): Failed to set up write-combining range" in Xorg.log
appears as well. Xserver performance is wrong too.

As you wish I send dmesg output and the contents of /proc/mtrr for
2.6.10-rc2 from my first computer.
