No, it is not the same message. Now it correctly detects disk2, but it 
lacks MAC OS X specific code for BIOS device guessing.

grub-install expects device.map in /boot/grub; so put it there (i.e. on 
filesystem on /dev/disk2s1).

Someone more familiar with OS X need to contribute device detection code 
for it.
