Every article I've read about the PSP so far has indicated that the PSP will not have region-locked games. But what's this? Scott (sar7501) has taken a picture from the packaging of Namco's "Ridge Racers" software for the PSP, and it clearly depicts what I believe to be a "region" icon. So does the PSP have region-locked games? o­ne of the PSP's primary developers, Mr. Kawanishi, even indicated otherwise in an interview [1]. 

I guess we won't really know until Sony makes an official statement, or the American version of the PSP is released. The icon appears just above the barcode, and has the number "2" in white lettering with an outline of a sphere. Note that Japan's DVD region code is also 2.
