I've been following this in a very casual way, so maybe it's already
been offered, but the Linux kernel source contains a lot of
documentation about VESA modes and VESA polling.
A quick whole-word grep for "vesa" in <source-tree>/Documents lists
several files in <source-tree>/Documents/fb and
<source-tree>/Documents/svga.txt
The source files and header files themselves are generally reasonably
well-commented, and should also be informative. It's all in the kernel
source tarballs available at ftp.kernel.org, or I could make an archive
of just those docs and the associated driver trees if anybody wants them.

But like everyone else, you've missed the
point. The OP was originally
asking about standard IBM cards, not about VESA "standard" cards which are a
different kettly of fish....

Actually, I think *you*'re missing the point of this whole thread, which is the
feasibility of 132 column mode in Dave's VT-100 emulator; FYI I'll quote the OP:
...
"Does anyone know if any of the more modern (ie: VGA) cards support enhanced
132 column text modes? - And is the video addressing basically the same except
for 132 words of memory per line instead of 80? And where to find more information?
If it could be reliably determined that support was there, and it is compatible with
my text windowing code, it would not be difficult to add support for it."
