	Actually my problem with the Supnik emulator is that the clock runs
	_very_ fast - the "PDP11" ends up being hours ahead of the real time
	after recompiling a kernel or two.

	p11 on the other hand tends to run slow - tweeking the device.c value
	was aimed at speeding up the clock.

	With a change to 'geni.c' or by editing the instab.s file?

	Yep - that's what I was seeing until I regenerated the instab.s file
	by running 'geni'.  The emulator would compile and link with a 
	manually edited instab.s file but simply would not run correctly.  

	Since the same RP06 image worked with the Supnik emulator I knew it
	wasn't in the 2.11BSD area.
