U-Boot and Etherstix

I would very much like to start booting using one of the network schemes:
bootp, tftp, nfs, etc.  The minicom, Kermit, flash copy, reboot approach
seems like the long way around.

As a side issue, I would also like to mount the root file system via NFS.

Is the required driver for the etherstix included in the default U-Boot
configuration?

If it is not included is it doable?  I'm not asking for someone to do it
although suggestions are more than welcome.

What do I need to buy/build (prefer buy) to program a new version of U-Boot
into the flash?  I realize U-Boot can program itself but that assumes that
the new version works.  Not likely - if I have to write the include the
network driver!

FWIW, I have a bunch of JTAG cables from Digilent and Sparkfun.
