Whats going on with the RSX? Have people abandoned all hope of getting hardware acceleration on current PSX firmware? (e.g. people have discovered that there is no way to get at the needed memory locations via current HV) Are people still reverse engineering the PS3 HV to find out if there are HV calls that can do the job? Are people simply avoiding any work towards HV (because of fears of legal action by Sony for example?)

Security is tight in PS3. HV code is isolated. I don't think any hacker ever found a way to dump it from a running PS3.
The other way would be to uncrypt a firmware update file.
We probably miss a public key or two to do that, secured tightly in PS3 as well... Or I may be wrong.
You still need fw<2.10 if you want RSX at the moment.

What he said. About the only thing you can do is to make various HV calls with various parameters and look at the return values. Most of the RSX stuff is done through trying to manipulate the pipe and objects you get from setting up the framebuffer and doing blits (which ARE part of the linux code).
