Well, in any case, i can assure you there are non such in an iBook.
That's for sure. The best that the chip can do is 8x8x8 with 8 bits
pad to speed-up graphics handling. Mind you, I can't see much of a
need for RGB 11/11/10 or RGB 10/12/10. Seems like overkill to me,
given that the reported human sensitivity is only about 100 shades.
Of course, one can easily find better uses for 8 bits rather than
wasting them as padding (eg special effects) :-p.
