hackintosh how do I tripple boot?

Windows 7, debian(or Ubuntu) and OS X snow leopard where Windows is alreadu installed and OSX is going to be installed at a later date(waitng for my disc to come in the mail)but install Linux now.
I want to keep the windows installation
Is this possible? I read about Ubuntu being able to work with the others but they all assume that you are going to install OSX first.

I'll let grub handle the booting. I'm not sure if OS X thinks that it's the only OS on the system like Windows does. I'll install Ubuntu last as it will recognize the other operating systems and configure grub accordingly.

how do I install OSX without disrupting my Windows installation? I don't have a OS disc for it, it is an ASUS laptop with a hidden recovery partition or I could restore from DVD's but I can't do a clean install of Windows because the first thing that it does without asking is delete all partitions(even on the secondary drive) and installs NTFS with MBR.
