That's a 10/100/1000 PHY, right? Do you mean that you've booted uClinux
on the board but the kernel doesn't detect the PHY or do you mean that
you've looked through the uClinux source and you don't see a reference
to that PHY? Either way, don't PHYs have a pretty standard interface?
Shouldn't it be pretty trivial to add support?

I haven't used uClinux on OpenRISC myself (I tried to build it once but
it failed to compile), but I have used the OpenCores Ethernet MAC in an
OR1200 SoC implemented on the Digilent XUPV2P board (which uses an Intel
LXT972C PHY). I think much of the original OpenRISC development (e.g.,
the ORP) was done on an Xess board, possibly the XSA-50 that's currently
for sale on eBay. I mention this in case you're still shopping around
for a board. Academic pricing on the Digilent board makes it a bargain.
