The easiest way to do it is to unplug all your other drives, plug in the spare drive you are going to use for xp, set to IDE mode in bios, set the drive as the primary boot drive, cd-Rom as second, boot from the disc, create the partitions from the instal prompt, quick format and away you go. It's too much of a pain if you already have a raid setup because you will have to create the boot disc for the F6 install, these drivers need to be extracted and placed on the root of the disc, not in a folder. I did an XP install last night and ran into the above issues, unplugged everything as it went on no issues. Did all the tweaks, got down to 6-10 processes and still the same time as win7 :S will sp2 make much difference?? Not sure vs effort.
