Nope.  All current PowerPC OF implementations use a 32-bit
client interface though (to the best of my knowledge); this
implies that all phandle's are 32-bit.  If inode numbers can
be bigger than 32 bit, problem solved; if not, you'll have a
problem as soon as someone creates a 64-bit client interface
(as is strongly recommended for 64-bit systems).

But I think I see an easy way out...  you only deal with the
flattened device tree anyway, so just use the offset in that
blob?  Should be a nicely small number...
