Hello Don!
Some additional information about the bridge device 00:14.4 itself
(both legacy PCI cards are behind this bridge device - it's an output with both
legacy devices plugged in):
00:14.4 PCI bridge: ATI Technologies Inc SBx00 PCI to PCI Bridge (rev 40)
(prog-if 01 [Subtractive decode])
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop+ ParErr-

If the bridge is put to the VM too, libvirt exits with the following error:
error: internal error Unable to reset PCI device 0000:00:14.4: no FLR, PM reset
or bus reset available
The wlan device looks like this:
05:07.0 Network controller: RaLink RT2800 802.11n PCI

Latency: 32 (500ns min, 1000ns max), Cache Line Size: 64 bytes
Interrupt: pin A routed to IRQ 21
Region 0: Memory at fdae0000 (32-bit, non-prefetchable) [size=64K]
Capabilities: [40] Power Management version 3
Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA
PME(D0-,D1-,D2-,D3hot-,D3cold-)

Thank you for your advice,
kind regards,
