What makes you say that you can't run both disks if XP says it is on C and
Vista says it is on C?
Whichever drive is not booted will become D.
You will be able to access both drives.
I would disconnect the XP drive.
Install Win 2000.
Install Vista.
Make the Vista drive the first drive in the boot order.

Reconnect the XP drive.
Use vistabootpro to setup a dual boot.
If something doesn't work, all you have to do, is disconnect the Vista drive
and XP will boot.
