The etch-m68k installer worked for me, with the kernel command line
arguments "suite=etch-m68k modules=etch-support".

You can also use debootstrap. A while ago I wrote some messages to the
list about the former method, and Geert and I wrote a howto for the latter
method. (By now it probably needs a few tweaks for recent Debian/Ubuntu
releases.)

There was a post on the mailing list reporting that a Net Install for
etch-m68k is possible by copying the ISO to an HFS partition.

The toolchain I built was a cross-compiler. I never built native binaries
for binutils and gcc, and I didn't package the eglibc binaries.
I did tar some kernel binaries, which probably have the TLS/NPTL patches
(it was a while ago, I don't recall exactly):

This kernel should work on a Q650. I do have such a machine, so I may be
able to help if it doesn't work on yours.

Yes, it is complicated. The sid source packages for linux, eglibc and gcc
need patches, but that's the easy part.
The difficult (and slow) part is building and rebuilding everything in the
right order, with the right hacks to resolve circular deps.
Cross-compiling side-steps a lot of those issues but it isn't any use for
Debian buildd's (though it could work with Gentoo/m68k).
BTW, latest upstream binutils and GCC releases already have TLS/NPTL
support for m68k. The git repos for glibc and Linux appear to have
TLS/NPTL patches merged, but not yet released.
