Assuming it must be free + open source, does anyone have any recommendations? 32 bit minimum. I was looking at the plasma on opencores. Has anyone done a uclinux port or thought of doing one? Conversely if someone wants a uclinux port to plasma I'll do it for $$$. :)

David,
how much $$$ are we talking about? I am looking for open-source core with uclinux, but OR1K is too large

I think the leon3 is smaller then the or1k.. But if im wrong ill be corrected :)
its also 'standard' so all the tools/os/etc are out there today. Less development.
There was a pretty good thesis called "Evaluation of synthesizable CPU cores" (google for it) that compares the LEON and OpenRisc (also mircoblaze). It goes into resource utilization, performance, etc.
I am currently using OR1200. I did read this Evaluation of synthesizable CPU cores, I seem to remember it as being biased towards LEON...
Anyways, > There was a pretty good thesis called "Evaluation of synthesizable CPU

well LEON3 single project use license is 20 KUSD and OR1K development is also already commercial
both are way too largish when we are looking for minimal FPGA CPU that can boot uClinux.
LatticeMico32 is possible the smallest 32Bit RISC that is uClinux capable, but there is not known if there will be any uClinux development done for it.
besides the above there are some MIPS like cores that are potential candidates to be ramped up to boot uClinux.
but there is still a need for any 'minimal' cross-vendor FPGA CPU that can boot uClinux IMHO

BTW this discussion moved to email, discussions of money are somewhat delicate...
