I really wanted to keep it covered until i had ironed out all the
remaining bugs but since so many people asked about it, here is the first 3.5 kernel for Q/omap4:

deb package:
http://people.canonical.com/~ppisati/ti-omap4-tilt-34-on-35/linux-image-3.5.0-205-omap4_3.5.0-205.10_armhf.deb

git tree:
http://kernel.ubuntu.com/git?p=ppisati/ubuntu-quantal.git;a=shortlog;h=refs/heads/ti-omap4-tilt-34-on-35

entire pile of patches that i integrated:
http://people.canonical.com/~ppisati/ti-omap4-tilt-34-on-35/tilt-3.4/

where "done" contains the patches i integrated(1304), "already" contains
the patches already present upstream (369) and "skipped" the patches that
weren't relevant or left for later evaluation (35), for a gross total of
1708, plus some uplevel/fixup patches i created during the porting.

tarball of the aforementioned patches:
http://people.canonical.com/~ppisati/ti-omap4-tilt-34-on-35/tilt-3.4.tar

original git tree where i get the patches:
http://git.linaro.org/gitweb?p=landing-teams/working/ti/kernel.git;a=shortlog;h=refs/heads/tilt-tracking

What's broken:

-analog audio output is broken - a large portion of audio support was
already upstreamed but the remaning patches didn't apply since the
upstrem stuff was sintactically modified - and when it happens it
usually means the commiter didn't want to let the old stuff apply for
some reason - thus i need some time to sit down and see what's going on

-a couple of processes (hwclock and hybrid-gfx die on startup)

plus there are a couple of warning during boot (iva_seq0|1 and
temperature alert for the sdram (but this one was present on 3.4 and
linaro kernel too)

What's working:

-video output
-serial console
-usb (mass storage, mouse, keyboard, etcetc)
-freq. scaling
-mmc
-ethernet
-wifi

Tested on a PandaES and Panda rev a4.

I created a tracking bug so people can report their success/unsuccess
over there:

http://bugs.launchpad.net/bugs/1035289

if you identify a problem check if it was present in Q/omap 3.4 too (e.g. the emif warning that NO ONE reported so far and i found by myself this morning...), and
write down a simple step-by-step guide to reproduce it.

What's next:

- fix all the trivial warnings and the on-boot dying processes
- rebase on latest Q/master (we're still at 3.5-rc6 here)
- import all the config changes already queued in Q/omap4
- import latest patches from agreen's tilt/tilt-3.4 

(i'll probably cut another release here)

and then sit down to get the audio situation sorted out.

Have fun with testing, but remember that is a WIP kernel.
