The 32bpp is broken or unsupported on all chips except Laguna ones (on Laguna I made it work a week or two ago). 2. Very little to gain from 32-bit (is the alpha channel used on fb?). The previous implementation just set transparency to 0 length. 3. It is supported only on Laguna and GD5480 (and I have only one Laguna chip to test). It should work on GD5436/46 but it does not (even X11 driver left it out). 4. Acceleration for GD5480 would be untested in 32-bit mode (Laguna has no acceleration anyway) - probably (surely) broken.
