Yeah it should work no problem. Where did you hear that about XP not having good SATA support?
If its SP2/3 you will be fine. Most Sata driver problems were from the original XP disk. If not you can just slipstream your sata drives to yor CD or just use the F6 promp with a floppy. I,ve install XP on a many AMD 700 series chipset and never had a problem. Just update all the boards drivers after you install XP.
