My Becker device has no problems whatsoever reading maps while  
maintaining a very tight fix, and I've driven all over Austria and  
never noticed such an issue.

Just because 'other' devices may also have design defects with  
software workarounds doesn't mean much, imho.  We're not coding for  
TomTom or Garmin, we're coding for OpenMoko.  Non-sequitur.

If its a suitable workaround or not can only be judged by actual  
application, not discussion.  The efficacy of this solution to poor  
hardware design can only be judged when the patch makes it into the  
mainstream, and when users - and developers - whiny or otherwise -  
push the fix into action and actually see the results.  Your point  
that we may not even notice the issue is taken; it remains to be seen.

.. or some other open-source cell phone or similarly configured open- 
source, Linux-based devices.  Its not like OpenMoko are the only ones  
who are making a lot of hype about the open nature of the project, and  
its also true that other devices being developed in an open fashion  
have better and worse aspects in terms of hardware design ..  
testing .. and the general snarkiness of their communities.
