If it has something called CSM, it should be able to boot FreeBSD:

In fact, Intel has been using EFI on recent motherboards such as 

They didn't say it on the web page but it does have EFI.

If the Apple hardware doesn't have CSM, then we have to make 
'EFI-aware' boot loader chain and add EFI interface (instead of vm86 
bios calls) to i386 kernel. :-(
