[PATCH] ne2k_cbus tidy up

When Osamu Tomita cloned ne2k_cbus from the ISA ne.c,
some of the version information, printks and so on were
not updated to reflect that it was indeed a different
driver than the original.  This tidy up takes care of
that and zaps the old changelog info which is no longer
relevant.

Patch is against 2.6.0-test5.

Thanks,
Paul.
