This is expected behaviour. The hw does not support everything, so instead of
advertizing all extensions and having awfully slow fallbacks, the extensions not
supported are not even shown.

paletted textures.

Hw doesn't support these, the driver could in theory provide some half-useful
fallback. But apps are happy without them and usually do the "fallback" on
their own just fine.

This is a bug. The driver does not support 3d textures (there are some problems
with this feature in hardware), you should get a (slow) software fallback (as
it's a 1.2 core feature it must be supported by the driver). Could you provide a
backtrace? Last time I tried that demo on radeon it worked.

I guess those two could be supported by hw, but the driver doesn't support it.
