I don't have any specific recommendations, but I can nominate some 
minimum specs to help guide your search:

FPGA - I think a basic microblaze system will fit in a Spartan 300K - 
though I don't think you'll get Xilinx' ethernet MAC in there as well.

RAM (SDRAM, DDR)- 4 MB is probably a useful minimum, 8MB would be 
better, and 16MB is lots of headroom!

FLASH - 2MB is enough to store the kernel and root file system image - 
some extra to put a r/w filesys (JFFS2) might also be nice.

IO - at least one RS232 port, plus whatever user IO (leds, switches etc) 
you are interetsed in.

I just checked XESS but they don't seem to have anythign suitable, and 
seem pretty heavily priced for what you get..  I've got an old (now 
discontinued) XS Virtex300K board floating around, I'm thinking of 
"porting" the mbvanilla platform to it.  Anyone out there got one of 
these boards who would find it useful?

I'll keep looking around, see what I can find.

How's their uartlite driver look?  Mine is based on mcfserial (motorola 
coldfire), which in turn is based on the "standard" 16650 UART driver in 
the mainline linux kernel.  I've nailed all the obvious bugs, and got 
signal handling working etc, so in fact I have a hard time crashing my 
shells these days!! :)

John
