No, this is not compatible with PSP in any way. For Linux on PSP, you need:
1. Old fat PSP with firmware 1.5 (because of kernel mode)
2. µLinux (because the CPUs do not have a MMU).
As far as I know the µLinux for PSP is not finished. You need also the fat PSP because of the infrared keyboard support.
Even I can't run µLinux on my PSP, because I have only a slim model.
