I'm not sure I understand what you meant by that.  First I added the 
both hw.pci lines to /boot/loader.conf and rebooted. Then I tried the 
following two scenarios:

1: kldunload if_wpi
2: kldunload snd_hda
3: acpiconf -s3
4: resume
5: kldload snd_hda
6: kldload if_wpi

However when I load if_wpi in step 6 it will not recognize the hardware.

The other scenario:

1: kldunload if_wpi
2: kldunload snd_hda
3: kldload snd_hda
4: acpiconf -s3
5: kldload if_wpi

This scenario again results in a panic when loading if_wpi in step 5. 
When loading if_wpi again the following message popped up in particular:

wpi0: chip is in D3 power mode -- setting to d0

Allthough when I checked the second scenario again without the hw.pci 
lines in /boot/loader.conf the this message also appears when 
re-enabling wpi.

Is one of these scenarios what you had in mind ? Or can/should I try 
something else ?

Thanks for the help so far
