no real problem - you simply did not select the modules necessary .
cd /usr/src/linux
make menuconfig
Network device support --->
Ethernet (10 or 100Mbit) --->
[*] 3COM cards
....
<M> 3c90x series "Cyclone/Hurricane/Tornado" support
<M> 3c590 series (592/595/597) "Vortex" support
you can try compiling the modules only
make dep
make modules
make modules_install
probably it would be best to rebuild completly so
cp .config myconfig
make mrproper
cp myconfig .config
make oldconfig
make dep
make modules
make modules_install
make bzlilo
and reboot to rtlinux
