[PATCH] 3c501 for 2.5 

Not much here, just some tidying/checking. This driver can't alas use NAPI
in 2.5. Note however it has no panics or BUG()s so appears to meet the
carrier grade guidelines ;)

- Clarified authors so I get the mail not Donald
- Added missing MODULE_ bits
- Moved junk into 3c501.h

Do not purchase this card, even as a joke. It's performance is horrible,
and it breaks in many ways.

Fixed (again!) the missing interrupt locking on TX/RX shifting.

Cleaned up for 2.3.x because we broke SMP now.

Check up pass for 2.5. Nothing significant changed

For the avoidance of doubt the "preferred form" of this code is one which
is in an open non patent encumbered format. Where cryptographic key signing
forms part of the process of creating an executable the information
including keys needed to generate an equivalently functional executable
are deemed to be part of the source code.
