Please realize that there are 2 drivers which support this card for 2.2 
kernels: 3c59x and 3c90x, the second from 3Com. They have different code 
and different behaviour; they also have different options, so please try 
to be clear about what you have tried.

That's exactly what I'm talking about: you want to use the 3c90x driver, 
but specify options for the 3c59x driver... This won't work!

With the above setup that's no wonder. Please go back to the initial(?) 
setup with:

alias eth0 3c59x
options 3c59x ...

if you want them to work. You can get some info/debug from 3c90x too, but 
you'll have to figure out yourself how and what it means...

>From the vortex- and mii- diag output, I would guess that you have some 
default media in the EEPROM of the card set to something else than 
autonegotiate. Please use 3Com's DOS utility (3c90xcfg.exe, you should be 
able to find it on floppies/CD or on 3Com's web site) to set both speed 
and duplex to "auto" or "N-WAY". Then also set the switch port to 
Another solution (not recommended): set the switch to 100Mbit, then use 
module option 4, or even better use "mii-diag -A 100baseTx" or 
"mii-diag -F 100baseTx" after loading the module without options.
