Ouch!  Do you have a buggy whip to keep the system at a trot ;-O

Ahhhh, on your system that likely means there was a PCI clock issue.
The bus and processor are slowed when on battery power.

I'm guessing that you are encountering the Sleep Mode bug in the chip.
Check that SLEEP mode is not turned on with
  eepro100-diag -ee

No...  a 3c509 isn't going to be overloading your laptop ;->

Autosensing works fine.  The 3c509 doesn't have autonegotiation, and
full duplex would overload the ISA bus anyway.
