Well, due to flaky board design, you may not be able to utilize the max
speed because of interferences etc even if the devices would support it.
Such knowledge of flaky boards could be encoded in the ACPI tables, or?
But probably not in the client device, hmmm...

I don't know enough about real-world ACPI tables to suggest a best
practice here. I just wanted to add that busses < 100 kHz are legal from
how I read the specs.
Oh well, Jarkko liked the patch, so let's all sleep over this patch and
if nothing else comes up, I'll apply it tomorrow or so...
