That's piece of information is hardly useful. Linux could be doing any
number of things that Win95 that would prevent VESA 2.0 calls from
working.

I'm seeing conflicting information on this. And the Hercules Dynamite card
I purchased not _that_ long ago doesn't have VBE 1.2, let alone 2.0, in
the ROM.

I don't doubt that it would be useful to use the VESA calls if they are
available, I just doubt they are widely available.

Don't forget, VESA is hardly a universal panacea -- if it was, this whole
thread wouldn't be happening.
