This will break systems not using the local APIC since you unconditionally
call lapic_setup() on resume.  This was part of the feature of the previous
code that by using a dummy pic it could register it only when the local APIC
was used.  It should also be registered before any of the I/O APICs are by
the design of the local_apic.c code.
