I think that obtaining verbose boot logs for both cases would be a nice start.
If you can't get the log as a text (e.g. via serial console) for the APIC case,
then a series of digital camera screenshots would be fine too.

P.S. Here seems to be a dmesg of FreeBSD 7 successfully booting on T43 with APIC
