I don't know if there are, but there certainly could be because abiding by the old VBE mode numbers (eg: 101h = 640x480x8bpp) is not mandatory! They could use almost any other number for that mode instead. Hopefully none of the vendors out there are that stupid.

Quite. It's just a pity that it's the 15 year old boy on 2 weeks job experience that gets to write the VBE implementations these days.:-P

Yes.

It was years before the VBE specs were freely available. Before that you had to spend a lot of $$$ to get them.

If it's only implemented on a few, then it may as well not be implemented on any.:-(

I wish VBE will be keep as long as is possible on new VGAs.

I think Linux might be our saviour here, because AFAIK, it is still used as the "last resort" video driver on that O/S.
