A proper fix is headed upstream now:

There were a few problems here:

* The DCON detection problem above.  I've solved this by just changing
 the test to point to a driver that's actually upstream:


* The current HEAD was segfaulting, also now solved in the driver.

* I eventually worked out that "modprobe msr" is needed before starting
 the driver on Rawhide -- if you don't, you get a screen full of white
 snow.  We'll need to get this logic ("if on an xo, do modprobe msr
 before X starts") into Fedora proper somehow.  Any ideas?

Is there anyway to detect and load this using HAL rules?

I'll release a new version of the X driver into Rawhide within a day or
so, and the kernel patch above should make its way into Rawhide via
Linus at a similar pace.  Once both of these are applied, I'm happy to
report that I can get to a functional GNOME desktop, using Sebastian's
olpc-gnome kickstart file.

Is this on the net somewhere?


Yep, it is, indeed. ;)

Here you go: http://dev.laptop.org/git/projects/fedora-xo

I've recently modified the olpc-desktop.ks - it's now the one which includes GNOME as well as Sugar, so that you should be able to switch between them.

Any suggestions are greatly appreciated! BTW: The final image file shouldn't be much bigger than 300 MB...
