Tested against current git (v2.6.27-rc6-158-g9824b8f) and looks good.
Attached the patch with Rene's Signed-off and my Tested-by for 
convenience.

I had not tested earlier as you said you wanted to better understand the 
cause first. Did you get anything more about why things happen as they do 
from the info I sent?

Attached also a dmesg diff for boots with the two different BIOS settings 
with this kernel (with Rene's patch having filtered out the "io resource 
overlap" messages).
It still clearly shows the difference in how some devices get enabled and 
how their resources get assigned.

Cheers,
FJP

PNP: avoid checking unitialized BARs for conflicts
    
Avoid checking a PCI BAR for conflicts if the BIOS left it unitialized.
