Actually INIT 31 only does an InitGraf on 64K ROM machines and Mac II's
- not Plusses or SEs.  The relevant code looks something like:

		tst		Rom85
		bpl.s		not64k
		<lots of stuff for old ROMS, including _InitGraf>
not64k		<stuff for all machines, but no _InitGrafs>
		btst		#$e, Rom85  ; Yes, #$e
		bne.s		loadinits
		pea		-4(A5)
		_InitGraf
		_InitPalettes
loadinits	<load inits>

(This is from the 6.0.2 INIT 31 - your mileage may vary.)  So _InitGraf
is only called for 64K ROMS and Mac II's or higher.  Anyone at Apple have
any idea why?
