Please try out my repo:
For x86_64, it gets completely rid of compile time APIC_IO and
introduces a loader tunable hw.apic_io_enable. Right now it does not
compile non-SMP, but I will fix that later. Also i386 is not yet
supported, again, it's pretty easy and straightforward to bring in i386
If we commit this to master, I'd like to see the distribution shiped
with an SMP kernel as well!
