Short answer: you CAN'T call that VESA (1.2) routine from pmode as 
pointer. You either have to do it with int 0x10 or use VESA 2.0
pmode-extensions (which btw is a lot faster in any case!).

Okay, there MAY be a way to do call that rmode-server, but why bother?
DJGPP has to switch in rmode to do so and later then back to pmode,
so any possible speed improvement is lost anyway.
