Probably because architecture stuff and bit length in 32-bit is half :)? 
Instruction set's a bit different too. There are some new features in 
the new Intel processors like overflow protection, etc, so I wouldn't 
doubt there are differences in ISA at the assembler level.

Yeah, but grub provides more power in choosing your load options though. 
Besides, gag has an ugly bootloader screen >_>.. I only use gag when I'm 
not afforded a choice with FreeBSD's bootloader and then grub.
