Do the "remove the Linux disk and move he XP disk" technique
you mentioned to install WinXP onto
what it believes will be the primary disk.... then...

Then switch things to put the Linux drive back as the
primary and the WinXP as the secondary.

You can try something like this inside of grub.  Notice the
map commands in particular.

title WinXP
map (hd0) (hd1)
map (hd1) (hd0)
root (hd1,0)
savedefault
makeactive
chainloader +1

Let us know if this works for you.
