Please try this patch and send me the results of 'sysctl dev.pci' and
'sysctl dev.pcib' and 'sysctl dev.cbb'.  There's 0 chance it will fix
the problem, but will let us know for sure if this is my 'problem 1'
or something else.

This patch is against today's -current, but may apply, maybe with some
fuzz, to earlier versions.
