i got it working for sf4 and nba2k11, a combination of the right .KO and openbm, most of my non 3.42 games also work like blur etc..

how i got it working...
i have reflash my n900 to the stock kernel
ive installed psfreedom gui from extras-devel
replace the .ko in "/opt/psfreedom/modules/omap1" with the pl3 .ko
opened openbm.1.17.2
start sf4 and the rest works...

however i can see that it freezes sometimes. compared to the older open backup manager and power kernel ko's ...

another thing is. maybe the reason it didint work the 1st time is because im using the commandline to lauch ng psfreedom (./psfreedom-enabled.sh)

when i switched to gui program everything work smooth and easily,

i hope this helps for others also.....
