Yep, that's 16-bit, it needs its own IRQ.  I use a 3Com 3CCFE575CT 
(3c575) that
I purchased just because my old PE-200 was 16-bit and messed with the modem.

Or when you want to use the modem just pop out the network card.  Two 
ISA devices
can have the same IRQ as long as you don't try to use them at the same time.

You might also exclude IRQ 10 in /etc/pcmcia/config.opts and see if the 
card will then use
IRQ 7.  7 is for the printer, but Linux can poll the printer port for 
simple uses like printing,
though if you need to use one of the faster modes for the parallel port 
(like I have a webcam
there) then that needs the IRQ all of the time.

Good luck
