Do you mean that there are vendors who implement specific videomode number as different resolution/depth than as is described in VBE 3.0 spec? This would be really bad! Theoretically it may happen for mode excluded from spec but I belive they are smart enough to not make a babel from it.

Anyway we should be satisfied there is a such VESA standard allowing setting SVGA modes same way on diff HW otherwise it would be really mess with many drivers and even nobody will now support DOS so we would left with VGA only.

Unfortunately the standartization didn't get further - to get some BIOS functions for 2D primitives and block transfer would be nice. There already was an attempt with VBE/AF but AFAIK they wanted too high license fees from vendors so nobody adopted this standard.

So currently VBE 3.0 is the best we can get (even maybe FreeVBE/AF on few adapters). I wish VBE will be keep as long as is possible on new VGAs.
