This is the beginning of support for VT3230 (K8M890)
for the xorg unichrome driver.
The current status is that it seems to be able to draw
enough to display a gdm login screen. Something is not
working properly in the acceleration initialization so
it's horribly slow, a lot slower than the
I've tried to port over as much as possible from the
sources released by VIA, but I could not manage to
figure why the 2D acceleration is not properly
initialized. The PDLL code is just copy pasted from
VT3108 since I did not understand that part of the driver.
It's not in a usable state, but it's a beginning.
Information about the PDLL generation gladly accepted,
especially how to port over changes from the driver
released by via.
