The problem is that Windows doesn't like it if it thinks it is not on
the first partition of the first hard drive.  Fortunately, GRUB can
trick it using the map parameter.  Try using the following entry in
/boot/grub/menu.lst:

title		Microsoft Windows XP
root		(hd2,0)
map		(hd0) (hd2)
map		(hd2) (hd0)
savedefault
makeactive
chainloader	+1


That should take care of it.  It did for me.
