The drivers work, but they need a "shrink-wrap package"?
They aren't interesting for actual usage, but all you need is a way to use them legally?
So what's going on? Do they work or not? If we could get them legally in a "shrink wrapped package," would they be "interesting for actual usage"?

I stand by my admonishment of TI until I see a tangible difference.
danramos: TI wants as much as everyone to be giving out quality drivers. Current issues is not due to OMAP2 or their drivers, but due to the way the N8x0s are set up regarding external LCD controller as I've explained

TI has been cooperative in the port of these drivers to N8x0, so I think it's a bit unjustified to think they should 'feel shameful' as they have been forthcoming in delivering sources and libraries from their side.

Right, let me explain the timeline:
* I got GPL drivers and libraries from TI quite early. The kernel drivers are GPL, libraries came with no license. The GPL drivers and libraries are -for OMAP2-, which means that we would have to adjust them for N8x0 setup, which proved to be the difficult part.
* Since they (libraries) came with no license it was impossible to make them downloadable publically of the sole reason that I don't want to risk maemo.org or myself a C&D - I hope that you respect that.
* We had a few community members (who has been involved in the request to get drivers in the past) who knew what they were doing test out the build systems of the drivers and try to get the drivers initializing and rendering.
* Initially, everything failed. By chance, we figured out there were some bad assumptions in the drivers (regarding number of framebuffers and some kernel structures) which got the drivers initialized.
* Then, javispedro managed to get the drivers rendering under X (one of the former posts).
Currently, the drivers render straight into the OMAP framebuffer. Which some know, isn't enough to make it actually appear on screen (contents have to be manually synchronized to the external framebuffer). With a framebuffer synchronization call after each render request, it did update synchronously and this was not rendering very fast. That's the hack curiousity.
Current situation re licensing is that TI is making a shrink wrap package of the libraries that we can actually pass around. We have also requested information in order to get WSEGL (windowing system) headers so we can integrate the MBX rendering better with Xomap and may possibly push frame rate higher.
Right now the path we are pursuing is similar to kate's comment on https://wiki.maemo.org/Talk
rivers_justification (The 'We are having discussions with TI if we could find reasonable terms to get driver released to developers etc' part).
To get further development on this driver, we have to have it out in the open properly and that is what happening right now (TI responded positively this morning). Since the drivers are for OMAP2 they need further adjustment for the N8x0 setup, where community members have already given a hand in getting them to work for N8x0 and hopefully more will happen in this regard.

The drivers are there. Just not ready for general use yet. Mer will have them once all issues are fixed.
