Hello,
I have a 865G too, the only combination that works for me with the
i915 intel driver is:
kernel: gentoo-sources-2.6.28
driver: xf86-video-intel: 2.7.1
Anything above that (>=3Dgentoo-sources-2.6.29, >=3Dxf86-video-intel:
2.7.1) fails for my setup with freezes like the ones you describe.
As my box is ~x86, I have installed many versions of xorg-server
without varying the kernel and driver, and they worked all right.
I am thinking in giving up to using the intel driver in order to user
the latest kernel, with an /etc/X11/xorg.conf using a VESA card
configuration and I have not tested the i830 option.
Hope this helps.
