Confirmed the netbsd-5 tree runs fine with the change and pullup submitted.

One question - could I confirm the syntax in simh-vax for the cpu idle conmmand?
Am I missing anything?

sim> show cpu
CPU, idle disabled, 256MB, HALT to SIMH
sim> set cpu idle
Command not allowed
sim> set cpu idle=VMS

thats with a load -r .../ka655x.bin and set cpu 256m

Thanks!
