If you want to do a network install you have to modify your initrd.img to include the specific network kmod.
That's what i did for the eeepc/CentOS 5.2 network setup You can also create a repo then that can be used during setup so that the network kmod will be installed on the filesystem too and that you have network access after the first reboot without having to manually install the driver/module
