If its not on the cnet compatibility list you probably won't be able to use it, sorry.
I have a 16bit PCMCIA card too you see, and this is not cnet compatible. So being old and relatively slow is no guarantee it will work for you. It depends on the "chipset" I think.
In the end, there's only one way to find out... :-(
Edit: cnet does support some 100mbps cards - the coder of cnet chased me up about that one. ;-)
