Subject: 8-bit alpha in 32-bit frame-buffer?????

Are the 8-bits of alpha in a 32-bit frame-buffer used by game developers for anything?

If they are used, then how are their absence dealt with in a 16-bit (565) display?

Do most modern games simply ignore this storage facility?

Can they be used to do sort-independent translucency?

How can this be achieved when combining alpha info with an opaque texture completely obliterates the alpha channel information?

 

Thanks :-)
