Sure. In the end, installed Lenny, added a squeeze chroot then rebuilt
the squeeze kernel with old-style IDE support instead of
pata_cmd64x. That worked fine as a workaround.

We're using a serial console already, in fact. No output. But the
machine starts warbling and flashing LEDs as though it's caused some
kind of machine exception or something. Not sure, I'll see if I can
find a manual.
