Only on Intel Macs.
First you have to boot the OS X installer disk, and use disk utility to convert disk to MBR (you can do it in the windows installer, but it's not as easy). then in the Windows installer delete all partitons so it makes the system reserve partition if desired.
it might be possible to boot windows via EFI on 64bit Macs, but it is difficult and if you mess up resetting PRAM doesn't fix it.
You may find that it takes a while to boot, in which case you can run the following command to make the Mac automatically load the BIOS bootloader:
# bless --device /dev/disk0s1 --setBoot --legacy
Run it from Disk Utility on the OSX installer, and if needed make sure you substitute disk0s1 with the partition with the Windows bootloader.
i haven't done this yet, as I haven't had a chance to work on the mac.
