There have been a few posts over the years on problems with Win XP BSOD during
boot when trying to run the windows using the "old" kqemu accelerator with the
-kernel-kqemu option (accelerate guest kernel mode as well as guest user mode).
This issue is probably nearly dead by now, but for anyone who may still be
using this, e.g. on machines without the VT-X or AMD-V hardware, FYI I have
a developed a fairly small and (relative to kqemu itself) simple workaround for
this problem, that allows you to get some benefit from -kernel-kqemu without
resorting to other tricks such as disabling ACPI in the guest device manager.
The workaround is to defer use of guest kernel mode acceleration until after
the WinXP guest has completed the tricky part of booting (dynamic guest RAM
allocation). Then, in effect, -kernel-kqemu is turned on and full
acceleration is available.
So booting is dismally slow as before but after that it runs quite well.
Works for me for 32-bit WinXP guest and 32-bit linux and the following qemu
releases:
qemu-0.11.1 kqemu-1.4.0pre1
I don't know about 64-bit, W7 or Vista as I have never tried them, but the
same idea may work.

(Anyone know if there is an upload area for contributors? If so I'll put it
there - the two patch files are small)
