After firmware 6.30 Sony added ECDSA signing to all firmware files (on top of the original CMAC signing).
Game files still only have CMAC signing, so you should still be able to check which tag it's EBOOT.BIN needs (the int value at offset 0xD0), but this tag needs to extracted and resolved from mesg_led.prx (just like all the others were), which is now ECDSA signed.
Currently, all hopes rely in the remote chance that Sony could have made the same mistake in the PSP as with the PS3 (as in http://en.wikipedia.org/wiki/Elliptic_Cu..._algorithm ).
