Hey!  You're comparing apples and oranges here.  I assume OS/2 is like
Windows in this area, which means they cheat.  All blits that I've seen
in Windows are aligned, meaning both the source and destination for the
blit are on the same bit position within the display memory.  That's
a huge win on a VGA.  I'd be suprised if truly general blitting were
any faster.  If you've got other examples of things that are faster 
under Windows or OS/2, I'd be very interested in hearing about it.

Not that I don't need to get a lot smarter, but I'm willing to 
argue this example a bit.  :-)
