How? We *know* we're deviating from the behaviour of Windows here. What
we don't know is how that will affect different machines. I suspect
we'll end up with a bunch of "Well, I added this boot option and then my
system booted slightly faster" and have no ability to work out whether
the problem's actually related. See the number of people who reported
that acpi_apic_instance made a difference, or even the fact that Thomas
included a bunch of systems with no real assurance that they were hit by
this.
A static list will eventually end up either filled with false positives
or missing several machines that should be there.
