At first, you don't need VMWare if you don't want to run other operating systems as virtual machines.
Second, running Mac OS X on any other hardware than in Apple's computer is problematic (from hardware and from EULA point of view).
You don't have to use Partition Magic for disk partitioning.
If you want to run all those operating systems as virtual machines, you can just create one large partition, install VMWare to Windows XP, and then install other operating systems from VMWare, and create virtual disks, without need for disk partitions.
You can also run OS as a virtual machine from physical partition with VMWare.
Dedicated operating systems
If you don't want to run virtual machine(s), you have to partition your disk and install capable bootloader.
Configuring Windows XP, Vista, 2000, 7 and Linux to same bootloader can be a little bit tricky operation, but I would start by installing Windows 2000, then Vista, then 7 and finally Linux. While installing Linux, you can choose to install
grub (Linux bootloader), which can be used to boot to Windowses too.
