Yep; I'm OK with the i8042.noaux from my point of view, but it's a
bit worrying that this used to work fine.  There's obviously been
a change somewhere since 2.6.18 (and as I remember from the dmesg
the keyboard and aux ports are being initialised in different orders).
(Actually I say obviously since 2.6.18 - but the 2.6.18 I tried
I think I only used the debian version - I should go back and
see if I can do a vanilla one), but this box has been running
Linux since the time it was originally bought with loads of distros
and clean kernels years ago.

While this machine is old, the motherboard was a pretty common one
at the time.
