The patch under consideration is to restore pre-2.6.25 behavior (i.e.,
active mux) for machines other than the one in a particular bug report,
while 2.6.25 broke my machine. So this will probably rebreak machines that
were broken until 2.6.25 (and can't break anything else). I think it would
actually be better if we could apply the quirk to all models of 3000 N100
except for mine (but I don't think quirk-matching supports that); my
model is the only one we know of which came with a BIOS that has issues
with legacy mode. I still think it's weird that Lenovo managed to break
active mux when they'd had it working before, but who knows what's going
on in their firmware development process.
In any case, I suspect that the legacy behavior on my machine is strange
but manageable (given that Windows doesn't seem to have had problems using
legacy mode even on my hardware, so far as I can tell), and we should be
able to cope with it in general.
