+Subject: viafb: Autoload on OLPC XO 1.5 only
+Bug-Debian: https://bugs.debian.org/705788
+Forwarded: no
+
+It appears that viafb won't work automatically on all the boards for
+which it has a PCI device ID match.  Currently, it is blacklisted by
+udev along with most other framebuffer drivers, so this doesn't matter
+much.
+
+However, this driver is required for console support on the XO 1.5.
+We need to allow it to be autoloaded on this model only, and then
+un-blacklist it in udev.
