The script has to be updated. I hope we can soon switch completely
over to .24 (also for GTA02). In the meantime, we will add a
conditional in OE to handle that.

This roots in the general flakeyness of the communication with the gsm
modem. Unfortunately no one had time or motivation to seriously look
into the whole issue of the modem becoming unresponsive at times.
There's a whole load of bugs related to that in the bugtracker. It
remains to be seen whether this is a gsmd bug, a kernel bug, or (god
forbid) even a yet-to-be-discovered hardware bug. Someone really need
to treat that with measuring equipment and/or jtag.
