Your kernel is missing drivers required to mount the rootfs.

root over nfs ends up being the unknown block 2,0 rather than 0,0 as  
it is in your kernel.

Make sure the drivers for your hard drives SCSI or SATA and PATA  
drivers are in the kernel, not as modules.

Make sure the filesystem driver to mount the rootfs is in the kernel  
and not a module.

Sincerely,

William Harrington
