Yes. The Milax loader tries to set up an alarm callback to display a 
twirly baton during the loading stage, so that would be a good test. Is 
it useful? Hmmm.... ;)

It just struck me that it would be a good test for SPARC64 interrupt 
handling in Qemu as it's something that can easily be tested from OpenBIOS.


ATB,
