I'd like to thank Tushar Dave publicly for his or her help diagnosising
and resolving the problem with the Gigabit hardware and driver under
Linux. I believe Dave works for Intel, though I could be wrong. So
thanks to Intel too, for their excellent support for Linux (the board
was several years old) and to Camaleón on this list for pointing me in
the right direction.
Along the way I switched to the current version of the driver (from
lenny); this produced noticeably higher throughput (peak c 450Mb/s vs
300 before, typical 300 vs 200). The driver itself did not resolve the
problem, which required a firmware upgrade.
The one fly in the ointment is that I continue to have network problems.
Although I believe the server ones are fixed, the laptop is still
dropping all network connections, including ones that don't go through
the server. The laptop is clearly in bad shape for a whole lot of
reasons. Broadcom provides networking for the laptop, but the ultimate
culprit is likely overheating from a bad nvidia graphics chip, or
perhaps some Windows Vista flakiness.
