I just tried loading viafb on a VIA Epia board (Unichrome CLE266) running squeeze, and the console is now broken. I can see the GRUB boot messages (from weeks ago) and a mess of dots in various colours. The module also has a whole lot of parameters which suggest that it may need board-specific configuration. So I don't think we can allow it to be autoloaded on the whole range of device IDs it claims. What if we apply a patch (attached) to match the specific subsystem ID on the XO 1.5? (I got this from the Openchrome source so hopefully it's correct.) This still leaves us needing to update udev and then worry about kernel vs udev versions, but it should cover the installer.

Subject: viafb: Autoload on OLPC XO 1.5 only
Bug-Debian: http://bugs.debian.org/705788
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.
