Sorry that it has taken me so long to reply...
I patched up the source in a few different places, mainly adding the
card to the list of known cards, and i got it all working nice and nice.
Though the problem with my comp not being able to do more than 640x480
was not due to bandwith calculations, it was due to the fact that i was
telling X to output to vga AND tv, but i didn't have the tv plugged in,
and therefore could not start it up with the requested video mode, and
was falling back to the barebones.
Now, my question is, since I got the code working, and i've been running
it for 2-3 weeks now, and there seems to be no problems, how should i go
about submitting the code?
Should I create a patch file and submit that to someone, should i just
submit it using svn... Or should i just tell someone the steps that I
followed to get this working?
Cheers
