Yes.

Do you think we make things without even testing if they work? Funny 
way to program ;-)

Normally is a MUST (capitals). Because VGA cards uses I/O ports in 
the 0x3Dx space and mono cards in the 0x3Bx space. 
Now ... if one of your VGA cards supports memory mapped I/O ports 
(some PCI cards support it I think most of the new models does) and 
you have some knowledge about video boards you can do it. But is 
*very* difficult if you don't know about it. 
Basically you must put out the BIOS of one of the boards (perhaps not 
needed for an ISA/PCI pair), cross your fingers, and if the machine 
boots program the card without BIOS to emulate a mono card. I know is 
possible, never tried.

What? I'm developing a video driver and I'm amazed of what RHIDE can 
do, of course, the VESA BIOS must be a good one. Trident BIOS looks 
very good.
