Interestingly enough, even with the HPET _CRS reverted to its state
before d9f5cdbdf, I get (with qemu git master, and with seabios git master
plus the reverted hpet):

qemu-img create -f qcow2 xp.img
bin/qemu-system-x86-64 -enable-kvm -m2048 -bios bios-master.bin \
  -cdom ./XPSP2.iso -hda ./xp.img

A problem has been detected and Windows has been shut down...
STOP: 0x7e (0xC0000005,0xf73b8d66,0xf7d1ea0,0xf78d1b9c)
acpi.sys - address f73b8d66 base at f73ad000, datestamp 41107d27

I may be biased in favor of the d9f5cdbdf patch :) , but is there a
chance removing/reapplying it is just tickling some other problem ?
