Windows XP Booting on Mac Contest Over [Update x3]

The contest to boot Windows XP on the Mac is over. The winners will receive $13,854:

Contest has been won - updates to follow shortly. All further donations will go into an account to sustain the open source project that will be launched with the initial solution.

The instructions to the contest stipulated the following conditions:

- Boot Windows XP on the Intel Mac
- Windows must coexist with Mac OS X and may not interfere with the operation of the other
- Upon starting the computer, the user must be offered a choice of which OS to boot

A photo of the OS selection screen was posted (mirror). Upon booting the Mac, an Apple logo appears on a grey screen. Pressing the down arrow key at this time brings you to a Windows logo on the same grey background. Hitting enter lets you proceed to boot the selected Operating System.

According to this post the final solution will work on the 17" iMac, 20" iMac, Mac mini and MacBook Pro. The full solution should be posted shortly and appears it will include downloadable bootloader.
Update: The final solution has been posted for downloading, but is receiving a lot of traffic.
Update 2:: Windows on Mac sub-forum has been created to organize discussion and troubleshooting on this topic.
Update 3: Support for the 20" iMac is not yet available. There is a FAQ available with a test version for the 20" iMac.
