What would be a good GNU Radio test on a 500 MHz PPC board, with a
USRP, but no display?

To just test that GNU Radio itself is sane, you can run the dial tone
demo in:

gnuradio-examples/python/audio/dial_tone.py

This will send a dial tone to the audio output.

You can test the USB <--> USRP performance using:

gnuradio-examples/python/usrp/benchmark_usb.py

If you have a suitable receiver board, you can test the whole system by
receiving a broadcast FM signal:

gnuradio-examples/python/usrp/usrp_wfm_rcv_nogui.py
(You need to set which receive side with -R and frequency with -f)
