OpenSUSE Install :: 11.3 Does Not Support Ip_pnp?

In OpenSuse 11.2 it was possible to pass the ip configuration on the kernel command line and the kernel would configure the interface (eth0 in my case) properly. The ifcfg-eth0 needed to be configured as 'static' and 'auto' with the other parameters absent. The kernel arg would look like: ip=<client-ip>:<server-ip>:<gw-ip>:etc:etc

This no longer works or works differently in OpenSuse 11.3, despite the fact that ip_pnp seems to be compiled into the kernel. Is there some way to enable this in 11.3? I just want to do basic static routing with the parameters passed directly to the kernel instead of hard-coded in the ifcfg-eth0.

p.s. in 11.3 when I try to do the ip_pnp method the eth0 does come up but none of the routing is correct. There is no default gateway and no ip is assigned even though I am passing the kernel args properly.
