I don't know about your card, but it sounds like a hardware conflict.
Those adresses refer *usually* to serial ports.. Try disabling your
onboard serial port(s) in the CMOS and see if that resolves your conflict.

Cardctl reports 0x02f8 and 0x03e8 both at irq5
serial_cs catches 2f8 but fails on 3e8
setserial reports /dev/ttyS? as an 'unknown' UART
0x03e8 irq5 so something funny is going on...
I'm running ppp through the 2f8 port and wondering
what the other port is for, is it even there, what's the story,
anyone know?
