Do you really mean 'boot multi-processor'?  Or finish the boot and activate 
multiple processors?

APIC aside, Linux is by no means alone in 'booting in UP'.

FreeBSD 7- and 8- in both i386 and AMD-64 do so as well, 'launching' adiitonal 
cores/CPU only aftr nearly everything else is done.

Real Time OS, 'Super Computing', & MIL-spec / aerospace apps aside, not sure why 
one would want to do otherwise...
