TI releases: http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/ ; perhaps also this: http://git.ti.com/graphics/omap5-sgx-ddk-um-linux.
According to Release Notes, the last SDK to support SGX540 is 4.04.00.04 (SGX core revision 1.2.0, gfx_dbg_es7.x / gfx_rel_es7.x folders).
Pandaboard (ES) might be a suitable test platform since it is very similar to the Droid 4, and there are/were Ubuntu releases for it:
https://nl.mouser.com/new/pandaboardorg/pandaboardES/
Ubuntu resources:
https://wiki.ubuntu.com/ARM/OmapDesktopInstall https://wiki.ubuntu.com/ARM/OMAP https://launchpad.net/~tiomap-dev/+archive/ubuntu/omap-trunk - TI OMAP-related packages, including PowerVR drivers
Ubuntu kernel module mirror:

Way to use TI drivers with modern X modesetting driver + glamor? https://github.com/TexasInstruments/dri3wsegl ;
There also exists leaked Android SGX540 DDK source code for OMAP4 device by LG, which is not linked here, but is easy to find and could be used as last resort.
Some notes from irc:
20:57 < Wizzup> NeKit: I made a stub page here - https://leste.maemo.org/Motorola_Droid_4/PowerVR
20:57 < Wizzup> feel free to add ideas, links/resources, etc
21:37 < NeKit> edited page a bit
21:37 < NeKit> so support was cut after 4.04.00.04 SDK release, makes me wonder why
21:39 < Wizzup> for what, for xorg or the older omap
21:40 < Wizzup> or sgx :)
21:40 < Wizzup> (all these names confuse me)
21:40 < NeKit> SGX540
21:42 < Wizzup> we should also involve nikolaus perhaps
21:42 < NeKit> it has SGX core 1.2.0 and folder suffix is es7.x
21:42 < Wizzup> ah, ok, I didn't realise it had that core
21:43 < NeKit> http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide#About_Graphics_SDK - notice 7.x is missing in
table
21:44 < Wizzup> what sgx does n900 have? I don't even remember
21:44 < NeKit> SGX530, not sure for core revision
21:44 < Wizzup> ok
21:44 < NeKit> N9/N950 is also SGX530
21:46 < Wizzup> http://www.ti.com/sitesearch/docs/universalsearch.tsp?searchTerm=SGX540&linkId=10&src=top&m=dd
21:46 < Wizzup> seems this is the latest pandaboard release http://processors.wiki.ti.com/index.php/RN_4_04_00_04?keyMatch=SGX540&tisearch=Search-EN
