There is a combination that would be interesting to try, the idea is to use QEMU to emulate an intel processor, and then try to install

Im mentioning intel because android-x86 is only compatible with a few intel processors (intel atom series mostly)
I dont think is going to have a great performance, but just for the sake of having android running in a PS3... this would allow to run android games/apps
*And i guess the same can be made to run microsoft windows... but is better to use an old version, like windows 2000, or windows XP
