1) inertia: fbdev has been around a lot longer, and provides most of what embedded devices need anyway 2) feature set: why bother doing a full KMS driver if you're not going to use any of the additional features it would provide (output management, memory management, execution management)
- its got documentation
My summer of code project's purpose was to create something of a tutorial for writing a KMS driver. The code, split out into something like 15 step-by-step patches, and accompanying documentation are available from Google's website.

My repository (doesn't include the documentation) is available here: http://git.kernel.org/?p=linux/kernel/git/mattst88/glint.git;a=summary
There's a 'rebased' branch that contains API changes required for the code to work with 2.6.37~.
It's nothing fantastic, but I've had a number of people tell me that it was useful for them.
Thanks, Matt
