With the tools apple provides, you can not change a serial number, but
you can program a serial number in to a blank board. If your good with
assembly you can modify the software to allow you to change the serial
number.
The tech you encountered did not do his job properly. The service
manual says that you must program in the old serial number. If you
take your machines to any apple authorized service provider (or anyone
else who has GSX access) they can do this for you.

What is the proceedure to "reset the serial number"? I've come
across a couple of eMacs that have had their motherboards/logic
boards replaced due to a faulty batch of capacitors causing the
infamous "melting screen" issue. None of them had serial numbers
when I looked at them using Apple System Profiler and when I spoke
to the tech that Apple sent out, he said that this was "normal" for
replacement logic boards. If there is a procedure to "reset the
serial number" that he's supposed to have done, then he's not doing
his job right, not to mention it's now a pain in the ass to keep
track of them sans serial numbers that can be seen via ARD.

Almost the only time that a machine won't report that it has a
serial number is after the logic board has been replaced and some
technician forgot to reset the serial number.

What macs store their serial number on disk instead of on the
logic board? Where did you find this information?

rather just
stored on the disk. In that case, just reformatting or replacing
the hard
disk will wipe the serial number. You should read this:
