azalia on DOM0 and HVM broken on 4.0

[Dima Veselov <kab00m%lich.phys.spbu.ru@localhost>]

Hello!

I have met a problem - my system can't compile in azalia support for XEN3_DOM0. 
My config is very simple:

include "arch/i386/conf/XEN3_DOM0"
ident   "Xon"
azalia* at pci? dev ? function ?        # High Definition Audio

Kernel compiles good, but on load it breaks in uvm_fault right after 
xen_timecounter is found (as I know that's the place of azalia loading.

Also after some changes in system configuration my HVM-win2k3 domain become 
unusable, saying on start "Cannot deallocate guard page for HVM (25 
Inapropriate ioctl for the device)

kernel give me a message:
Jun  1 01:59:21 laura /netbsd: sys_ioctl: _IOWR('P', 0, 24) returned -1: 
pid=107 comm=python2.4


xend.log shows:
