I don't know how closely you want to control the video hardware.  But,
I have a version of slightly enhanced vgl library which can do VESA
modes as well as the standard VGA modes (the version of vgl included
in -CURRENT and -STABLE cannot handle the VESA modes *sigh*).

Soeren and I developed it, but have not yet committed to the source
tree.  I can send you the new version for review if you like.
