That is not possible. Only the vesa set bank function can be used with a "far call" instead of using the software interrupt for to set the banknumber of a banked vesamode. The pointer(offset,segment) for this "far call" can be found in the mode-info-buffer+0Ch. On my older et4000 isa-bus card(1 MB) and et4000-w32 vlb-bus card(2 MB) i found the portnumbers(3CDh and 3CBh) for to change the banknumber in the code of that cards when i was unassemble this function in there bios. Trying the same on a geforce4 ti4200 agp card(64 MB) i never found those portnumbers, because i have many problems to follow all of the many branches in the code.
