Any acpi/lapic/apic options which are required generally represent bugs,
either in the BIOS or the kernel.  Either way, they ought to be fixed in the
kernel so that everything works out of the box.  This data collection could
help us do that, but only if it "talks back".

In many cases, these options are required even to boot or to detect the
CD-ROM properly, so it is important that these bugs be fixed or worked
around in the kernel, rather than with command-line options.

As others have pointed out, this kind of data collection fits nicely into
the hardware database project.
