------- Comment #22 from kh...@linux-fr.org  2009-03-05 00:53 -------
The unhiding quirk is only applied for machines on which we know it is safe
(that is, neither ACPI nor SMM are accessing the SMBus.) So this isn't related
to the resource conflict.

We could add a _hiding_ quirk for machines on which the SMBus _is_ used by ACPI
or SMM and the BIOS didn't hide the SMBus already, as was suggested by Thomas
in comment #20. This has the advantage that it can be implemented immediately
and it is very fine-grained. However, this would only work on Intel ICH-based
boards (and not even all of them) so this won't solve the problem completely.
It also has the drawback that the blacklist could grow quickly, possibly beyond
the size of the current whitelist.
