The one that looks like a HiFi, with 133 MHz 604.

I cannot test that right now (I don't own the machine, it was sitting next to
me at the Oldenburg Linux/non-ia32 meeting), but the owner promised to join
the mailing list, so I hope he'll do.

Perhaps the problem is related to the PS/2 mouse problem on my LongTrail. I've
always used a serial mouse, because Linux locks up if I insert the PS/2 mouse
(while Linux is running).

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
