I got one more thing to try:
diff --git a/src/acpi-dsdt-hpet.dsl b/src/acpi-dsdt-hpet.dsl
index d5aa3f1..8385ce4 100644

The complete definition for the HPET on my MacPro5,1 is below; along
with the 0xFED00000 value gleaned from the previous SeaBIOS version of
_CRS, I came up with the above. Hopefully it works for WinXP too...
Thanks,
