A few more notes. I tried a variety of other cards, such as a PCI modem (WinMode, ack), a WinTV card, and a PCI based 802.11 card. All of them enumerate perfectly. Perhaps it is a BIOS option ROM like you suggested earlier. The 3c90xC reference manual I found (http://people.freebsd.org/~wpaul/3Com/3c90xc.pdf) mentions an option ROM (and there is an Atmel part stuffed). I can't find any technical information on the FA331 (yet), so I don't know about it. But regardless, wouldn't enumeration have to occur before any option ROM could even be used?
