Thanks, I hadn't seen that wiki, but I had tried to install xf86-video-via-git with yaourt. At first I got an error necessitating I edit pkgbuild line "options=('nolibtool')" to "options=('!libtool')". Now I get this:

I also tried unistalling vesa, installing xf86-video-unichrome and running hwd -xa, but even with vesa unistalled it insists on it. The openchrome site (which seems the only of the 3 drivers offered by Mint) doesn't say it supports my chip, but the unichrome site does.
***Ok, Xorg -configure worked with unichrome, where hwd -xa did not. Wow, 1680x1050, someone pass the tissues.
