Nope, have just tried the adaptec and matrox millenium I (dunno if its got
dipsies, dint have to change any though ;-). 24bit Video modes are a bit
odd, the left 1/8th of the screen is on the right hand side. but 8 and 16
seem to work fine so far.

Cant do, only have one and the Creator already came with the box. The Xfree

I have seen one message about this but was not able to find out more. where
and how would I look for these? Would really like to get this fixed.
