Hey
What's the output of "lspci" and "lsmod" in a terminal? It's possible that you might not have a driver for it. I had trouble with an i810 chipset while installing FC1 a few years ago, but with FC2 it was fixed. Besides, RH9 is getting a bit old, why not try Fedora?
or Ubuntu?
Send me back the output of lspci and lsmod
Cheers,
Aaron
