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 
SE7520AF2:

http://www.intel.com/design/servers/boards/se7520af2/index.htm

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. :-(

PS: Sorry to bring up Linux here but Linux won't have the problem 
because Intel has added EFI support for i386:

and EFI LILO (for both i386 and ia64) is here:

Just FYI...
