[RFC] Initial OLPC Viafb merge

[Jonathan Corbet <corbet@lwn.net>]

The following patches are the beginning of an effort to move work done for
the OLPC XO 1.5 machine into the mainline.  What's here is basic support
for the VX855 chipset, I2C, suspend/resume, and the OLPC panel display.
What's coming in the future is a reworking of the viafb driver into
something resembling a proper multifunction device, GPIO support, and
camera support.  But I'd like to start here.

If there's no objections, I'll start a tree and get it into linux-next in
the near future, with an eye toward a 2.6.35 merge.

Thanks,

jon
