Maybe it was my bad when I tried it, but on my Macbook Pro, I can't get 
the bootblocks which load an i386 kernel under parallels to work for an 
amd kernel as a native boot via EFI.

so, I asked (on this list?) if boot should be multi-arch or not, and got 
no reply. Does this post from you mean that by design, the MBR and /boot 
*should* be able to load either an i386 *or* an AMD kernel?
