Bad news grub not compiled on a GCC 4.4.1 from MacPorts:

gcc-mp-4.4 -Iloader/i386 -I./loader/i386 -I. -I./include -I./include - 
Wall -W  -Wall -W -Wshadow -Wpointer-arith -Wmissing- 
prototypes                  -Wundef -Wstrict-prototypes -g -Os -falign- 
jumps=1 -falign-loops=1 -falign-functions=1 -fno-dwarf2-cfi-asm - 
DAPPLE_CC=1 -m32 -fno-stack-protector -mno-stack-arg-probe -fno- 
builtin -mrtd -mregparm=3 -m32 -MD -c -o linux_mod-loader_i386_linux.o  
loader/i386/linux.c
20:16loader/i386/linux.c: In function 'grub_linux_boot':
20:16loader/i386/linux.c:546: error: can't find a register in class  
'BREG' while reloading 'asm'
20:16loader/i386/linux.c:546: error: 'asm' operand has impossible  
constraints
20:16make: * [linux_mod-loader_i386_linux.o] Error 1

MacPorts don't use specific patch to build gcc so i think the behavior  
is coded somewhere in the gcc source code.
