I noticed that some time ago and took a quick look, but was too lazy to
actually change prism2_srec (i.e., I just removed time line from the
file like you did)..

Well, this 0413 at 0x0000118e is kind of odd beast.. It is the first
time I see a plug record for that kind of address. The same entry is in
the flash version of the firmware image, too. This word is the value
for HFODelay which is used for radio control, but I have not yet figured
out why this kind of address is used. In theory, prism2_srec could of
course try to do something, e.g., just blindly write at the given
address. However, I would first like to understand where that
information is really supposed to be written to.
