the XO-1.5 camera doesn't work, there are some funky graphics bugs on XO-1, no power management, DCON doesn't work right on either laptop, desktop switching lands you at a blank screen.
I recommend rebasing on the geode driver 2.11.9, which was just released by upstream. I've been testing it in Dextrose for about 3 weeks: it fixes all the known rendering bugs and has no regressions.
The XO-1 os1 build already has xorg-x11-drv-geode-2.11.9-1.fc14.olpc1
