     You could attempt some trickery with grub if you have the option of 
using it and if you are installing Win/7 to its own drive. Here is the 

Install FreeBSD on your first drive ;) the way it should be...

Install GRUB from ports or packages whatever you prefer.

Edit your menu.lst file to contain something like:
title  WINDO~7 ;)
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0) (hd0,0)
chainloader +1

Now reboot into your bios and turn off your FreeBSD drive and your 
secondary drive should remain and to Windows 7 as long as it is staying 
along the same lines as Windows XP will just accept your secondary as your 
primary drive C: and just install its MBR to that drive.

After your done reboot into your BIOS turn your FreeBSD drive back on.

Tada! you now have a bootable system where grub swaps your drives around 
for you and confuses Windows 7 into thinking its the primary C: drive and 
you can upgrade without touching the first disks MBR.

I have this setup running on the machine I am writing this email from and 
for fail-over sake if my FreeBSD disk takes a hike windows will pick right 
back up without even noticing the first disk being gone. I have also 
disabled my FreeBSD disk in windows devices just to be sure that nothing 
happens to it as a cause of windows.

Anyway... Hope this gives you just another option to consider.

Best of luck.
