They're faster than VESA 1 -- isn't that the point?  Being no faster
isn't a problem -- so long as they're fast enough for your game. You
shouldn't really assume that nothing better than VESA 2 will ever be
available.  I was really referring to VBE/AF and the built in chipset
drivers, yes.  I don't know what VESA 3 is, but Allegro supports that
too.

OK.  The conversion would only be necessary on startup in most cases 
(as I said, Allegro will convert all of your images on loading), but 
you'd obviously be causing more conversions later.
