I don't know specifically about Haswell, but OS X has been checking
for lapic_version >= 14 ever since 10.5, same check, same number.
The latest Intel manual I could find (Feb.2014) says (Vol 3A, page 10-11)
that the version is contained in bits 0-8 of the version register, and
that values are 0x00 for the 82489 discrete apic, and 0x10 - 0x15 for
integrated apic, all other values are reserved.
So I guess we could make it 0x15 and be done with it for a (hopefully)
long time :)
