I see that this is a Debian specific patch:
044_chips_default_to_noaccel_on_69k.diff
Instead of that patch, the attached patch changes the default to be
non-accelerated, but allows the XF86Config-4 file to override this.
This is my first time ever looking at X source code, and the patch
is untested, so please comment.
If someone tells me what to type in order to build test packages,
I'll do so and report back.
Thanks,
Dan
