Well, the DayStar PowerCache 68040 accelerator I have in my IIsi
doesn't like NetBSD - but then again neither does MacOS 7.5.5.
One of these days I'm going to work on the problem, but I do know it's
somewhere in the MMU initialisation.

My recommendation is, if the Mac has a 68030 processor, you can use
a 68030 accelerator. If it has a 68040, a 68040 accelerator will work,
but if it has a 68030 processor (like the IIsi) a 68040 based
accelerator probably won't work.

Oh, and I don't think the Radius Rockets work either. Anybody want
to confirm all this?
