I think that is just a warning - it matches what I would expect to see in
a fussy compiler.

As above.

That, too.

I suppose that is an error, but it only affects a couple of printf's.

That is worrying. With the CSR15 hack in the driver it consistently
finds the MII transceiver for me (dual processor PII, 2.0.33, gcc).

I debugged these hacks with the 2.0 series of kernels with 10baseT 
and 100baseTX connections, not your 10base2. I think the different
network type is one reason why you are having a problem with them, 
though I would worry about the failure to find the MII transceiver 
first!

I've been concentrating on getting a driver that will reliably survive 
our network manager unplugging the network cable and plugging it back 
into random 10baseT and 100baseTX connections on the same network some
minutes later, but I am safe from 10base2 at the moment!
