So, the answer is still yes, it should work. According to the specs (you can check them here using the serial of your machine), your 2006 MP has a SATA II bus (3Gbps). A SATA I drive will work, but it wont take advantage of the full bus speed. You can also check the Serial-ATA bus speed your system has in system profiler (About this mac>More Info, etc).
BTW, I don't think is a good idea to publish the Serial Number and Hardware UUID of your machine. I recommend you edit your last post and delete that info.
