Er, seriously? All of those are either completely useless or counterproductive...

The first 2 only work, respectively, in LGE and Motorola ROMs. They do nothing outside those 2.
The SF settings are useless in CM7 since we don't use that generation of the qcom surfaceflinger.
The stagefright options are the default, all of them (except disabling scan, which is stupid anyway. Why would you scan with the slower parsers?).
The last 2 are meant for devices without GPUs...
