I guess if try and error loading those generic network card modules doesn't work and no other card available then...
Try the hard way
Download SuSE's United Linux (available as usual: linuxiso.org)
Burn CD1 and CD2 (no need CD3)
Boot and install from those 2 CDs
Now plastic surgury
Install available SuSE's 8.1 rpms onto UL 1.0
Install apt for SuSE (needed to back YaST2)
Install fou4s (needed to back automatic YOU)
You won't regret until 8.2 available for download ;-)
Have a lot more fun :-)
