Well, I can think of at least two things that may go wrong.  Try the 
selective install program and add support for the secondary monitor
(I did this during the normal install...).  Second:  Make sure the card
doesn't have an interrupt conflict with anything else.  Most of these cards
come with a parallel port adapter which is usually set up as IRQ5 and IRQ7.
(My bus mouse is setup as IRQ5 and that's the default for a secondary
printer port...If I had both of these at IRQ5, I would imagine OS/2 would
have trouble initializing the mouse...who knows what happens if it got
into a loop testing for something and gets responses from both cards...)

DOS doesn't use the IRQs for printers and doesn't care, but I'd be careful 
under OS/2 and other more sophisticated, multitasking OSs (Unix, NT, for 
example).

There should be an option on the card to disable the extra stuff.  I'd 
start from there.  It may not be an option, though, if you can't find
the documentation for it.  

Good luck,

Jeff
