There are no reports on Uniwill or Linux Certified boxes at
linux-on-laptops.org and the reports for uniwill boxes at tuxmobile
are for systems that use a different video card. If you know of a
site where you can search for reports by chipset instead of box
manufacturer and model I'd love to hear. I've suggested the change to
Linux-on-Laptops and from their response it sounds like they are going
to use it.

Neither video_post nor vbetool turned the backlight back on. Intel
has a driver on their site for the card which I might have to try, but
I'm positive that LinuxCertified had a non-free deb installed for a
video driver. I can't seem to find the name of that deb in the
/var/lib/dpkg/status file. Is there a regex I can search for in
"status" to find debs that aren't from the ubuntu main archive? I
can't seem to find any info in the entries that I should search on.
I'm still waiting to hear from LinuxCertified on the issue. Hopefully
they'll respond early this week and have a solution.
