The beat goes off

I have a problem.

The ethernet cards in my laptop (debian) and my dual booted desktop will 
talk OK when the desktop is running XP. That is, provided I force XP to 
run the link at 10M, as it gets 99% failure at 100M.

With Linux (Mandrake) on the desktop, I cannot get them to talk at all.

I'm currently forcing the 3x59x driver to use 10BaseT-FD (I *do* have a 
pretty naff PCMCIA card, so I'll believe XP when it seems to be 
incapable of doing 100).

When I play about with the link (i.e. unplugging and re-plugging the 
cable), the laptop merrily reports "lost link beat", "found link beat" 
and "autonegotiation complete: 10BaseT-FD selected".

However, at the desktop end, it seems to do everything fine, except that 
it always finishes up with "Negotiation did not complete" (see below).

I've tried various combinations of everything. Nothing gets better 
results. I'm really surprised/irritated that MS manages to at least do 
10BaseT-FD.



Output on restarting 3c59x from scratch, with the laptop up and running:
