Quad Boot Update
Finally got it working!
I didn't have any success with easyBCD as both my Vista64 and XP operating systems were separate Ghost12 backups and restoring each did not go through the multi-boot installation process so easyBCD had nothing to work on.
So, went back to the fosk method (

http://ubuntuforums.org/showthread.php?t=767677 and
http://ubuntuforums.org/showpost.php?p=3303463&postcount=11) and discovered that there is a bug in Ubuntu 8.04 Hardy Heron grub installer that does clobber the main mbr which stops all the other legacy operating systems (including Ubuntu) from booting from rEFIt.
This time around I changed the installation procedure a bit and did the following:
Booted disk1 of Mac OSX and partitioned drive as per fosk method
From the utility menu (still on the Mac install screen) selected install from Time Machine backup to the Mac OS partition.
Rebooted when finished and checked Mac worked ok which it did - my restore also installed rEFIt.
I inserted the Ubuntu live cd and rebooted, chose Ubuntu cd from rEFIt menu and installed Ubuntu as per Fosk method.
Rebooted and usual problem of rEFIt not being able to start Ubuntu, so did the partition sync fix in rEFIt (as per
http://ubuntuforums.org/showthread.php?t=767677) booted the Ubuntu live cd and then did the grub fix (as per
http://ubuntuforums.org/showpost.php?p=3303463&postcount=11).
Rebooted and Ubuntu worked from the rEFIt menu!!!
Next inserted Ghost12 cd and booted to this from rEFIt and restored XP Ghost backup from an external usb drive then did the same for Vista64
After a minor fix to XP (using
http://icrontic.com/articles/repair_windows_xp) everything worked. Even rEFIt seems to activate the correct partition for Vista or XP and back again - so no conflicts!!
Instead of Ghost restores you could just do complete installation of Windows Vista and XP - if Vista 64 then download the Boot Camp with 64 bit drivers from "http://thepiratebay.org/tor/3991487/Apple_BootCamp_2.0_Drivers_(including_new_64bit-drivers)"
Now to see how long they all work!
Hope the above is of some use.
