Ok, here are the specifics:

I'm running an A3000 with KS V37.175, WB V37.52, and SetPatch V37.6.

I just re-wrote my startup-sequence so the very first three lines are:

	CPU
	SetPatch
	CPU

When I rebooted, CPU reported "(INST: Cache NoBurst) (DATA: NoCache NoBurst)"
both times.

So it's not SetPatch, it's not my startup-sequence, and I believe V37.175
is pretty recent (but I've been seeing this since KS V36.something anyway).
So what could it be?

I'm perfectly happy just putting "CPU cache burst" in my startup-sequence
if that turns out to be the answer, but I'm really curious as to why my
machine (and the few friends I have who also have 3000s) seems to boot
up with everything disabled except the instruction cache.  Thanks for
any ideas...
