Hallelujah! Besides lack of support for ftp or nfs installation, the
Mac OS installer was just plain slow, and took about three hours to
just install base36, etc36, and kernel. Installing the corresponding
NetBSD sets (with its 'sysinst' bsd.rd installer) took maybe 1/4 that
time (and that was installing via NFS, rather than local disk).

Yep, the Q605, LC475, and Performa 475/476 have identical
motherboards. There's actually a jumper that when closed, the machine
identifies itself as a Q605, and when open, it's an LC475. After
replacing the 68LC040 with real '040, I was all set to run A/UX (for
shits and grins, if nothing useful), until I discovered it didn't
support the LC video hardware. And the reason I have the Q605 in the
first place is because I was given an old LCII, which I promptly
discovered royally sucks, and after doing a bit of research, found
that the Q605/LC475 motherboard fits perfectly in the LC II/III case,
so off to eBay I went.
Perhaps I should post this to port-mac68k rather than misc, but I'll
be glad to test any new kernels on my Q605.

Yep, sounds like the "Gentoo syndrome", as parodied at funroll-loops.org.
