It depends on a lot of stuff:
- you need the correct drivers
- you need to load them via insmod/modprobe if you haven't compiled them
  into the kernel (this means you need those programs in your initrd)
- you could then hardcode the network config in your initrd with a direct call
  to ifconfig or use a DHCP client, which means you need to include the DHCP
  client and its libraries in the initrd as well (there are lots of other 
  things you could do here or even need to do here...)

Just google for some initrd howto, there are a few. Maybe they'll explain the 
steps you need to do more in-depth.
