PS3 runs GameOS, and *used* to be able to boot another OS ("OtherOS") on the fat PS3s until update 3.21 came out.
Additionally, the PS3 Cell processor is very very different from x86, and thus games would be very non-trivial to port to x86 (or the from a more traditional multicore cpu to the Cell, as was a big concern back when it started).
