I had a similar problem some time back and pulled my hair out for a week
trying to figure it out.
I will assume the drive with XP is /dev/hdb and that 
/boot/grub/device.map shows that as "(hd1)  /dev/hdb"

What I did to make it work was change one line.
   rootnoverify (hd0,0)
This works because now grub has remapped both drives.

However, you also have to say how XP was installed.
If it was put in as /dev/hda or /dev/hdb and was the only drive in the
system when installed, then moved to the slave position my suggestion
should work.  If it was in the slave position when installed and a
master drive was in the system then this may not work.
