To reduce memory footprint, recently I converted all textures to palletized images. Unfortunately I see white textures when mipmapping is enabled (6681 and N71). The textures appear correctly with mipmapping disabled, however the frame rate drops by 50% (from ~10 to ~5).

N95 displays textures correctly even with mipmapping enabled. However there seems to be no mipmapping happening (N95 seems to ignore the mipmapping hint with palletized textures). Also performance drops significantly (from ~20 to ~7 fps), another indication that the mipmapping is being ignored.

Also M3G doesn't seem to allow explicit specification of the mipmap levels!?

How to get around this problem?
