As Stefan Linz pointed out it may make sense to try a newer version
of U-Boot (top of CVS) whichincludes fixes for the ethernet driver.

First, did you configure kermit as described in
http://www.denx.de/twiki/bin/view/DULG/SystemSetup#Section_4.3. ??

Second, try "send /bin uImage" to make sure to use _binary_ transfer mode.

Sure. Everything is possible :-) But I have no idea how much work
will be needed to get this working on your board.
