What about non-pseudocolor modes with bpp <= 8? We still use the 16-bit wide
pseudo-palette in that case?
Alternatively we can always use the 32-bit wide pseudo-palette, so the test
for info->var.bits_per_pixel can go away (assumed there are no pixel sizes
where more than 32 bits are needed for the color information). Then a pixel
value is just an opaque 32-bit value (cfr. fbtest).
