Is there a "memtestppc", as well?

Listing bootable images showed a "check". When I gave that a run, it  
went for a while, to something more than 70% and then wandered off  
into the ether -- black screen, as if it openfirmware had put it to  
sleep, but it wouldn't wake up.

The Fedora 9 powerPC netinstall doesn't seem to have any alternative  
images at all.
