How? Tools Partition + 3 Instances of Snow Leopard Partitions on single HDD

This is what i want to do:

0: IBM Lenovo Recovery Tools Partition - Maintain as originally present.
1: iPortable Snow Leopard with Tools (From the .DMG)
2: SL Retail instance for X61T (Installed as per instructions on Thinkpad forums)
3: SL Instance for T61 (If above experiments are all successful)

Is this possible? If so, what & how should I go about it? Some high level guidelines would be great..
