The 'fx' and 'tx' connectors should be 100Mbit, besides which people
have been complaining about lousy perfomance in 100Mbit mode.

I may be wrong - I've never run it in 100MBit mode.  No matter what:
To be able to run decently in 100MBit (and to work with the 3C905B) it
would need to use the busmaster mode instead of the polled IO mode.
You can look at the Linux driver 3c59x.c (by Donald Becker) for details.
