Kicking off this line is enougth to make winxp boot.

The irq logic in patch 2/3 works with winxp too, when booted with
-no-hpet device manager shows irq being assigned to rtc, otherwise rtc
has the ioports only.  So there is no conflict for IRQ 8, /me wonders
why winxp bsods nevertheless.

I think it's better to just comment out the line and add a comment why
it is commented out.

cheers,
