Do you understand why you get this error??

It should be possible to disassemble the location (0x080630f1) even
though it's not part of any function (at least according to gdb, but
most likely it _is_ part of some function).  I'm still interested to
know what instruction it is that exists on P-II and above but not on
your basic Pentiums (Pentia?).
