I'm am in the process of trying to do IP Masquerading on a a box with Yellow Dog Linux 2.2 (for Macintosh) I ran dmesg and figured out that my expansion ethernet card was not detected. (The onboard ethernet worked fine) I don't know much about the card
and the card itself dosen't reveal much either. It just has a "MAC OS" label on it. I looked up the brand online through the MAC
address and I determined that it is a Sonic System Inc. card. Does anyone know where I might be able to get some drivers for this thing?

Any help would be much appreciated.

I don't know dink about macs, but I know how to poke through source, so try these:

modprobe macsonic
modprobe mace
modprobe mac8390
modprobe mac89x0
modprobe macmace

Those seemed like some of the obvious Mac network cards from back in the day. Check "dmesg" as you go to see if they bound correctly.

Luck,
