Yes, please, the output from "vortex-diag -ee". I'm curious to see what 
has changed; I might have missed something...

They must not! But there are some cards (and I haven't seen enough data to 
even start some statistics) that return bogus values when reading from MII 
registers if the default EEPROM media is not set to auto. This is not 
documented in any way and I (and probably Don too) have no idea about what 
is causing this and what can be done to fix it. It's only in these cases 
that the default EEPROM media setting counts.

Oh, if I'd have access to the source of their Windows drivers and some 
internal documentation I'd probably be able to explain this and maybe 
other strange behaviours. As I don't, I can't.

To my knowledge you're the first one that have tried this driver which 
fixed the problem. It's a good starting point...

Because 3Com did not document this behaviour and what to do to fix it.

Sure. If we'd only knew how...
