Few more things:

I never noticed that Pcsx-rearmed for Leste works fine with neon-gpu (builtin_gpu) plugin:
As Fremantle, it works only with stock CPU frequencies (or maximum 720MHz). It works full speed.

Games tested: Gran Turismo, Tekken3, Motoracer 2, FFVIII, ISS Pro Evo, Medal of Honor, Metal Gear Solid


Now i'll have a look at android-808 and clort previous work on DrNokSnes to get it working with Leste: I'm already able to compile/build it but get a segmentation fault when i run it on my N900 at the moment.
Not sure it will be easy to debug.
