No, the S3 (82c911) and ET4000 (Tseng) are definatly NOT compatible on
register level, so I'll doubt X11 running on it (with ET4000 drivers)!
Of course, there might be S3-drivers too, but I'm sure about it.

There are palette chips out there that can do
- 256 out of 256K
- 256 out of 16M
- 32K fixed
- 64K fixed
- 16M fixed
combinations of the above are possible and available.
But there's no such beast with 32K out of 16M neither announced nor
available (at least not from Sierra, AT&T, Brooktree or Inmos).
I know since I looked heavily into that stuff recently...
Ciao, Klaus.
