Hello all (or should I say the few who follow this thread ;-), Some more experiments: I was able to force re-camping by detuning the 32 kHz oscillator. I used a hot air gun (low temperature) and heated the open GSM modem for about one second when it was receiving the PCH. With the test network I get the same results as if I detune the timing of the BTS and with a real network I get a lost signal and re-registration (most certainly the difference comes from the fact that I don't have the encryption option for the HP8922 and so no authentication is required to register to the test network).
Still not an evidence, but some tendency in the direction of oscillator instability/interference problems as the reason for bug #1024. Sure, the short heating could also influence other parts but the traces show the same behavior as the one real #1024 trace I have, also the TOA values change so the heating most certainly does not just change for example the RF gain only.
