How would you do this, then? To pass this information you would
probably create the custom tags discussed earlier, right?

I'm not so sure. Keep in mind that the bd_info structure comes from
the PowerPC architecture, wher eit is (more or less directly) passed
to the Linux kernel. For ARM it is not such a natural thing to use.
And in the long run (when PPC finally starts using bi_recs) it may
disappear there, too.
