I try to explain all in english:
the card FA311 have an driver of national semiconductor in it, so the driver tulip.o is not the right !!
You have two possibilities:
1. you can download the driver for RedHat from Netgear by: http://www.netgear-support.com
. There the name ist at first fa311.o (for RH 6.x or 7.0) or natsemi.o for RH 7.1.
2. you can download the driver for RedHat from Donald Becker/scyld.com by: http://www.scyld.com/network/ethercard.html
. There you can get the more actual version of natsemi.o and additional other files for compiling the right driver for each kernel-version.
3. It seems you need the driver fa311.o for kernel 2.2.x and the driver natsemi.o for kernel 2.4.x - I hope that's right.
