[Openchrome-devel] DVI output for CX700 integrated TMDS

Hello all,

I have built a multimedia machine with a Via EPIA EX motherboard and 
have recently just realised that there is no support for using its DVI 
output without resorting to the VBEModes hack.  This has motivated me 
into looking at the driver code, and I'd like to help to write something 
for the openchrome project so that the CX700's integrated TMDS and DVI 
output can be used.

Is anybody currently writing any code to do this?  I wouldn't want to 
step on anyone's toes.

(I recently saw a post by Frans-Willem Hardijzer to that effect:
http://www.mail-archive.com/openchrome-users at openchrome.org/msg01238.html
.. I spoke to Frans, and he's unable to spend any time to work on the 
driver at the moment.)

I have a fair bit of experience with systems-level programming (though 
not with driver development specifically), and I've so far just quickly 
skimmed through the code from linux.via.com.tw.  If anyone here has any 
advice for me or if there's anything I should know before beginning, 
that would be much appreciated.

Kind regards,

Adam Szmigin
