Yes, it is. You must enable support for Neponset and 91C96 ethernet
adapter in the kernel compilation options.

If you boot the kernel from flash, but you want to mount a remote root
filesystem, then there is no need for a "special" bootloader. You just
need to pass the kernel the necessary NFS arguments. See
Documentation/nfsroot.txt for more details. Essentially, you must pass a
couple of variables :
nfsroot=<server-ip>:<mount-dir>
nfsaddrs=<client-ip>:<server-ip>:<netmask>:<client-histname>:eth0:off
Remember to activate the "NFS fils system support" and "root file system
on NFS" in your kernel configuration, under "File systems". Also
"Networking/IP kernel-level intiialization".
You can boot from a kernel image in a NFS server using BOOTP, but I
haven't tried this.
