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
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.
