Using GMBUS isn't necessary, its optional, you can still bit bang the
ports albeit slow as crap and I'm no sure that isn't causing my
problems with the DDC over sDVO... my code only bitbangs the ports, my
GMBUS code is disabled if you look at my latest i830_i2c.c it works
for a while but doesn't interpret the status returns very well...

Probably don't bother putting DDC eeprom on the panels, cheaper by
about 10 cents...
