A new board may support more states than an old XP-era board but I would have though it'd still need to support the original ones too, because as time has passed there have become more advanced states.
JBI may be right in that it's buggy and untested with XP because XP isn't worth the effort, but since ACPI controls power try disabling all the power-saving features you can find in the BIOS.
Another (probably fruitless) possibility is that XP isn't understanding AHCI properly, which ties into ACPI and is often the cause of OS-boot bluescreens on older operating systems. If it's okay to trash the second OS, try putting the SATA mode to "IDE" instead of ACHI.
