Im using your patched sis_drv.o for X now. The performance increase is
noticable, but the Xv display still can't keep up with any highbandwidth video
(even 352x288 mpeg), so my dream of DVD playback is still far off but a lot
closer. ;)

Sure, when they are well supported reference designs :)

The SiS Framebuffer has the problem thats been mentioned where it
does'nt talk to the CRT/LCD controller correctly. It displays to the
CRT _almost_ perfectly, but sends garbage to the LCD, i guess its the same
for you.

I will never understand the logic behind a company _not_ helping produce
drivers for their hardware under our favourite OS. The only reason i can
even think of is if their hardware needs huge ugly hacks that binary
drivers hide.

done.
