Anybody who has an ATI Mach64 GT (RAGE) with chip ID 0x4754 and a revision
number where (rev & 7) is 0?

Revision encoding is defined as: mmFFFMMM, with
  - mm: minor revision
  - FFF: foundry
  - MMM: major revision

AFAIK, only the following revision codes exist: 0x01, 0x41, 0x1a, 0x5a, 0x9a,
which map to revisions 1.0, 1.1, 2.0, 2.1, 2.3.

Atyfb has some tests for (rev & 7) and (rev & 3), but if I'm right, these are
always true, and can be removed.

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.
