Which development system for use with GNU/Linux

I’m looking for a Rabbit development system. It should have a Rabbit 2000, 3000 or 3000A processor. There should bwe free commandline tools available to upload my binaries to the Rabbit development system. The development system should also have a serial port.

Basically, I want to:
Compile dhrystone / whetstone / coremark with sdcc, and transfer the resulting binaries onto the Rabbit. The benchmarks then run on the Rabbit, and their output goes to the host system via RS232.
