From what I've read it appears that the actual GPU is built into the
Northbridge with integrated 8x AGP but the output is handled by
different chips depending on what format you want to output in (ie
Composite, VGA, LVDS). The chipset homepage is here:
http://www.via.com.tw/en/c-series/cle266.jsp and apparently the LVDS
chip is a Chrontel 7019A (VIA's part number for it is the LVDS-01).
I've uploaded the PDF datasheet for the LVDS-01 here:
http://www.fuzzymuzzle.com/uploads/LVDS-01.pdf I'll Google this chip
and see if anyone else has had any luck with it on Linux.
Thanks,

Thats because thats normally a bios/vbios type deal. When you are
dealing with a panel direct its a whole different ball game.
Do you know if the LVDS is part of the EPIA video system or if its
seperate descrete chips?
LVDS has a couple of flavors depending on what type of panel you are
talking to. So the vbios will normally query the system bios for a
panel type or some bios config setting. Based on the panel type it
will set the internal chip registers or toggle gpio lines to put
descrete chips in the right mode.
CRTC Timeings are also panel specific. There are VESA timeings but
lots of panels still need tweaking.
some linux fb drivers and X drivers can deal with these issues but for
legacy VGA mode the vbios enables some video sytem trickery.
