On the VideoMaster 32, the 8bits of overlay IS alpha channel.  You'd use it
for menus, mouse pointer, and overlays.  This is what most videoboards for the
Mac feature.
 
A framebuffer doesn't necessarily have to be passive...they aren't on Suns,
Apollos, etc.  With the TMS34020, very fast interaction is possible.
 
The resolution is another question.  The 1024x512 could have been a typo, but
I'd doubt it.  Since it IS dual framebuffer, the two put together would equal
1024 x 1024...definately creative advertising.
