Looks like almost all changes to this driver had been tree-wide

The driver is using virt_to_bus() and is a real magnet for pointless
cleanups. It seems unlikely to have real users. Let's try to shed
this maintenance burden.

Removing this driver will kill support for some rather old PowerMac
models (some PowerBooks I think, paulus would know). No objection on my
part, though. I doubt people still use these things with new kernels
but ... who knows ? :-)

Aren't these PCI, and thus working fine with the PCI-only DE2104X
(dc2104x) or TULIP (dc2114x) drivers?

IIRC, I've initially used the de4x5 driver on Alpha (UDB/Multia) or PPC
(CHRP), but switched to the TULIP driver later (that was before the
dc2104x/dc2114x driver split, hence a loooong time ago).

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
