intel 815 with kernel 2.6.10

["Marco Berizzi" <pupilla@hotmail.com>]

Hello everybody.
I hope this is right mailing list.
I have a problem with X 6.8.1 and
linux 2.6.10 on an HP Vectra system
i815.

When I run X, the display show only
grey/blue garbage. However the mouse
pointer is right (I can see it).
This only happen with linux 2.6.x
(tested 2.6.9 and 2.6.10). Linux 2.4.27
and 2.4.28 are fine (this is a dual
kernel system).

My env: Slackware 10 gcc 3.3.4
glibc 2.3.2 X 6.8.1

I have also removed MTRR from kernel
2.6 compilation but same behaviour.

PS: Please cc me. I'm not subscribed
to this list.

This is dmesg and lspci output:
