Unfortunatly I don't know much about the VIA chipsets, but if the values in the VT1625Table represent register values it should be easy (i think) to add a table row for PAL modes. To determine the correct values for these registers we should install Windows, including the VIA Display drivers (I asume the TV Out works for this driver !!???), and set the TV Out to the desired mode. Then we read out the register values and add them to the VT1625Table. Sounds plausible?

Yeah, sounds like that might be possible but I really don't know enough
about any of this do it.  Also I haven't got a copy of windows anyway!
I presume that the lines in VT1625Modes are X modelines, and the
lines in VT1625Table are register values, but I'm way out of my depth
here...

I haven't tried the via drivers, I heard they were pretty crappy! I
think i read that they're for XFree rather than X.org too, but I could
be wrong.  I did download the source and have a bit of a peek.  Looks
like the tbl1625.h header may have what we need, but I've no idea how
you'd go about translating that into entries for VT1625Table.  Anyone
know if this is possible?

As I said I'm out my depth here but if someone who knows what they're
doing could help I'm happy to try out patches.  As long as they don't
blow up my telly :)

Cheers,
Alistair
