Boot of 9.1 under qemu-kvm 1.3 hangs at pci probing

[Bruce Cran]

I'm trying to install FreeBSD 9.1 in a Proxmox KVM, using qemu-kvm 1.3, 
but the boot process is hanging:

pbib0: matched entry for 0.1 INTA
pbib0: slot 1 INTA hardwired to IRQ 9
ioapic0: Changing polarity for pin 9 to low
found -> vendor=0x1013, dev=0x00b8, revid=0x00
                domain=0, bus=0, slot=2, func=0
                class=03-00-00, hdrtype=0x00, mfdev=0
                cmdreg=0x0103, statreg=0x0000, cachelnsz=0 (dwords)
               lattimer=0x00 (0 ns), mingnt=0x00 (0ns), maxlat=0x00 (0ns)
[hang]

Has anyone come across this before and know of any workarounds?
