Your FSB wasn't detected correctly (or rather not detected at all, what's
your CPU?). The actual bug is that if fsb frequency is too low the kernel
will crash when trying to use 64-bit mode (you can use -legacy parameter to
put xnu in 32-bit mode). You need to specify fsb with a variable. Can you
come to irc.freenode.net#grub ?
(e.g. for 200Mhz: set fsb=200).

-f parameter isn't actually used. Use xnu_kextdir if you don't want to use
mkext
