I doubt it, I think it's sun4u thing only.  There used to be
publically available a program that would use the undocumented
ioctl calls in Solaris to set or clear the time-of-day wakeup
counter on the sun4u.

I've placed a copy of the program here, in case someone wants
to have a go at implementing something similar in netbsd:

Trolling through the relevant sections of OpenSolaris might yield
some interesting datapoints about which bits need to be set in the
TOD chip to make it wake up the machine.
