Are you sure? I have not used recent SMSQ/E much, but I seem to remember a speed difference between running SMSQ/E from ROM and DRAM on the Q40 at versions 2.9x. ROM on Q40/Q60 is mirrored at two locations by hardware, so having two start addresses does not necessarily mean relocation.

Yes, but it does not spread over the whole 64K, not even 48K, at least on the Q68.
