[U-Boot-Users] amcc glacier board ethernet does not work?

I have an amcc glacier eval board, which came with u-boot installed, with working ethernet. The amcc folks told me that the u-boot was built off the denx 1.3.3 repository, so I cloned git://git.denx.de/u-boot.git and built glacier. It comes up all right, but reports

Net: No ethernet found.

along the way. The I tried cloning git://www.denx.de/git/u-boot-ppc4xx.git and building it from there - the same result, no ethernet interface up. Does anyone know if this is something to expect, or has something gone wrong?

TIA, vadim
