Well, just to clarify this: it's not insane because of this.  All
8514/A-descendant cards (to the best of my knowledge, including all S3
chips, and in particular all Mach's, since they are [or were] register
compatible with the 8514/A) clash with the port address 0x2e8.

The crime of ATI is that their newest chips are disturbed by writing
to register 0x2e9 _even while the card is not yet in `enhanced' mode_.
All the other mentioned chips don't do it.
