"Trying to get the thing to work on a modern
distribution, the first thing you notice is that it's messy code.
The kernel driver consists of a copy of about half of drm, with all
sorts of stuff included and built that doesn't really need to be.
And it's not remotely in sync with current drm. All it really ought
to be is a few files which should have rapidly been merged into
Mesa upstream. There's even a comment in the code that shows the
authors are aware of this, saying that one fairly trivial change
should be done before the code is contributed upstream. But the
change hasn’t been done to any Tungsten-, Dell-, Intel- or
Ubuntu-sourced version of the code I can find, so it’s still
a mess languishing in its own repository.
"The second thing you notice is it doesn't build with any kernel
post-2.6.24, due to that issue and a couple of others.
"The third thing you notice, if you're lucky, is that it's not
even really the latest version of the code, and this is where
things get really odd. As I mentioned, the copies of both the X
driver and kernel module in moblin.org git have not been touched
for eight months. However, squirrelled away in dank corners of the
Ubuntu empire, you'll find rather later versions of the code."
