Might as well add a post to this thread...I followed the instructions to a peg and I have two quick questions:
1. Can I install Windows 7 AFTER I've already installed SL? I followed seven18's instructions and have it EFI booting with Chameleon.
2. If I let SL set the date/time automatically, when I reboot I get the "Hold the power button to turn off your mac" error message. I have to go into BIOS and roll the time back 4 hours, and then it works fine. It never used to do this, but I recently installed a Dell Wireless Card (1510) in my Wind and ever since then it's been more and more picky about booting. If I roll the time back four hours it works 100% of the time. It's annoying, since I look up to see what time it is and it says 11:14am, instead of 3:14pm.
