You probably had ACPI as a module before.  You need to compile acpi into
your kernel if you wish to use it still.  These messages are from the
PnP BIOS probe that happens when ACPI is not used.

Yes.  As long as you have 'device apic' in your kernel config,
APICs will be used to route interrupts even on UP machines if
the machine includes an MP Table or ACPI is being used and it
contains an MADT.
