Yes.

With what has been discovered, we have 70% of full RSX power.
(the missing 30% comes from the impossibility to access a few registers that activate massive caching and automatic compression in tiles).

Nothing prevents homebrewer to obtain 70% of top quality professional GameOS software on PS3, with full usage of second memory part (so total free ram is around 200+252Mb).

The probability of the hole closure in a future firwmare update is close to zero.

PS3 has become a very very interesting machine now (especially with price at $399) whatever is its planned usage.

How easy will this be to take advantage of?

Currently, russian developer IronPeter is acting as an incredible project leader. He's incredibly well experienced with Nv30/Nv40/G70 Nvidia chipset families (RSX belongs to one of them). And he got a damn strong motivation and all the knowledge to create a fully usable graphic library.

Install cygwin (if you don't have any Linux) and type in

svn checkout svn://svn.pspdev.org/ps3ware/trunk

That will download on your hard disk, in current directory, the lastest version of the source of the library libps3rsx. I still have hope that, later, specific Linux kernel installation can be avoided and ps3link will appear, compatible with that library, allowing easy compilation and transfert from PC. Probably in 2008.

So, you just need to wait until his library is finished. Easy enough?

EDIT: Glaurung is incredible too. He's working mainly on linking IronPeter's work with existing high level Linux modules (Xorg, etc...). He just managed to create an independant context. I.e two separate processus can maintain independant graphic environments without too much slowdown when switching (quite necessary for high level Linux modules).

Glaurung did it! He managed to reuse IronPeter's libps3rsx into a Xorg module compatible with currently available Linux distros! If you are a Linux user you can now join the fun on PS3!

EDIT: CAUTION! Will work ONLY for firmware <2.10 (i.e last one ok is 2.01)
Avoid 2.10!!!

It's done, many tutorials are now spreading allowing noobs to install 2D hardware accelerated Linux distros on PS3.
Debian, Gentoo, Ubuntu, Fedora 7... You have the choice.

Of course, you need firwmare < 2.10 in order to get fast graphics through the enhanced Xorg driver.

However, we know that maximum graphical power on PS3 will be achieved by a mix between RSX and SPU's.
It shouldn't be too hard to have the RSX part disabled automatically if fw>=2.10 and replaced with something similar but unfortunately less powerful...

So, you will probably see future releases of homebrew software having different performances depending on your firmware version (2.10+ or below).

If you want to be part of the hardware accelerated Linux bandwagon, it's not too late to offer your 2.10 PS3 for Xmas to a member of your family and purchase a new one with older firmware (you have 24 hours to clean it and wrap it...).

Any links to these tutorials? I'm a noob to linux, but figure this would be a good time to play.

One for fedora 7 (very easy to follow for noobs) has been announced.
Will appear soon.

EDIT: fc7 tutorials drafts online, follow same link above
