Hi Thomas
In the last couple of days I've tried to set up Ubuntu 12.10 HF following
the instructions on [1]. While most things work as expected, I haven't had
any success in setting up a somewhat accelerated Xserver. All I get is X on
the framebuffer.
Here's what I've tried:
a) I've installed xserver-xorg-video-omap (Here's where the confusion
starts: Is that the neon accelerated one? Wasn't that
xserver-xorg-video-omap3 in previous releases? See below...)
This old neon driver is bitrotten/no longer usable, and the plan is
to replace it with, Rob Clark's xf86-video-omap...
http://cgit.freedesktop.org/xorg/driver/xf86-video-omap/
b) I've built and installed the sgx modules (once again following [1])
The "sgx" ddx is too old (abi wise) to be usable in ubuntu... *side
note, with the new release of "4.08.00.01" i'm playing around with
re-doing an "ubuntu natty" sgx image, althought it's now EOL, the xorg
abi's match.. However nothing is public yet. 
c) I've run the provided script "ti-omapdrm.sh" successfully and the result
shows up in Xorg.0.log:
This fails, as it requires the kernel to be built with
"CONFIG_DRM_OMAP" support, which i just haven't thrown the switch yet
to enable by default in v3.6.x..

isn't surprising - there's no such thing as omapfb.so anywhere in /usrSearching for hints, I've come across [2], however, trying to install the
deb-package provided there results in an error:dpkg: dependency problems prevent configuration of xserver-xorg-video-omap3:
xserver-xorg-video-omap3 depends on xorg-video-abi-12; however:
Package xorg-video-abi-12 is not installed.
It's dead, should be removed from the archive...
So it appears that the new version of X doesn't support that neon
accelerated driver. Next I tried to compile the code from [2] natively,
however, the build fails. I don't know where to go from here (belonging to
the Joe User category rather than being a hardcore developer, I think I've
tried all the straightforward options). Any ideas on how to go on would be
appreciated.
I'd recommend for a "right now" for Joe User, use the default
framebuffer as is. The recent "ti-omapdrm.sh" script push is just a
sign that i'm starting to get the ducks in the row in the git repo.
(as i use that same repo when testing)... But "today" it's not
ready...
