OK... If I'm understanding this correctly, it means that NewWorld  
Mac's can boot either from the on-board ATA or one of these OF- 
supporting SATA controllers  (possibly with some tweaks to ofpath to  
deal with any peculiarities of the non-Apple controllers) but *not*  
from most non-OF-aware controllers.

I, for one, can live with that as long as I've got some small ATA  
drives I can use for the purpose.  All I have to put on it is the  
"apple bootstrap (HFS) partition" and /boot, right?  But root and all  
the rest can be on the big SATAs, right?

It's not "beautiful" or elegant, but it is a reasonable work-around  
for a problem that we can't fix in the Debian environment.

Or am I missing something?
