USB chipsets are very generic and almost anyone of them you run accross will work with the usb-uhci or usb-ohci core driver. Basically, the odds on you having to return one are low enough so as to outweigh the time spent tracking down one that works for certain. Make sure that the PCI bios of your board and the minimum requirements for the card match. For instance if you get a usb 2.0 card its most likely going to require a PCI 2.2 compliant motherboard, which that early Pentium board certainly is not. Also, hope that the board you have is at least PCI 2.0 + compliant. If you don't know, just get it to boot to install and then open a console and look at the output from the command:
dmesg
for a chunk like this:
