Thanks Steve. For some reason I don't have the CONFIG_ROOT_NFS option in my kernel.
My problem is much the same as the one described on this page:
http://forums.gentoo.org/viewtopic-t-337239-highlight-.html?sid=f0de502989c707746fcebef76a1267d1

However, I had all the following enabled but still to no avail:
CONFIG_IP_PNP=y
CONFIG_IP_PNP_DHCP=yCONFIG_IP_PNP=y
CONFIG_IP_PNP_DHCP=y
CONFIG_IP_PNP_BOOTP=y
CONFIG_IP_PNP_RARP=y
CONFIG_IP_PNP_BOOTP=y
CONFIG_IP_PNP_RARP=y

I also tried "make CONFIG_ROOT_NFS=y world" and no luck there either.

Thanks,
Ardy

  There's your error.

  You need "CONFIG_ROOT_NFS" - that allows the root filesystem to
come from NFS.

  This article gives a brief overview from the last time I did this,
obviously not your distribution but it might be helpful:
