Fair point.

I think the important goal for GRUB is to provide an easy way for
ordinary users and a complicated but still useful features for experts.
So I propose always using simple aliases for drives. If you want to use
a device name provided by your firmware explicitly, you could use this
kind of syntax:

devalias foo "/address@hidden/address@hidden/address@hidden/address@hidden,0"
multiboot (foo,0)/boot/kernel

I suspect it will be a point of confusion that a user can directly use "hda" (a real/OF devalias) for their first disk, but if they want to use their second disk they must add a devalias command to their menu.lst file (or in OF itself).

Also, when booting without a menu.lst, now we need to enter two commands. Not difficult, just a little more awkward than it could be.

But on the whole this solution sounds pretty reasonable to me.
