These arguments are all well and good, but unfortunately based on a
false premise.  The roms are in fact in sockets, at least in my mac,
which is an earlyish one, and the extra address line to the roms is 
already in place (or so I have heard).  If Apple won't sell me the 
new roms, I'll be sorely tempted to get them some other way, I'm 
sure.
