Trick Photoshop CS5 - Multiple cores

[The Makakos]

I installed iPC 10.5.6 on my old Dell Optiplex GX620 without a hitch and everything works great. However, the PC has a Pentium 4 processor. I BOUGHT (i really did) photoshop CS5 for mac and didn't bother checking the minimum requirements. CS5 install went FINE the program even opens the Splash Screen but then a message shows up saying something about "This computer doest meet Photoshop CS5 minimum requirements" something like that and when i checked the minimum requirements on the adobe page, it states that you need to have more than one core. So my question is, is there any way I can manipulate system files to state that I have a pentium dual core or a core 2 duo or a quad i7, ANYTHING really I dont care i just want to be able to run the Program so i need photoshop cs5 to think i have more than one core.
