Believe it or not, so do we. Mr. Swindells and myself are both on the
NetBSD/mac68k mailing list, and have been known to do the occasional bit
of kernel hacking.

The calls to SetMMUMode() are used to set the mode to 24 or 32 bits
explicitly and they don't save the current mode setting. Beyond that I
suspect it was just that the machines at the time didn't support 32-bit
mode for user code. I'd make an unflattering comment, but the people who
did the damage might see it and I might need their help later. ^_-
