With FSO/SHR you might see problems related to loading almanac, ephemeris and 
time when powering up the GPS. The docs suggest that even with incorrect or 
outdated data the TTFF should be no worse than an unaided start, but in 
practise it seems that it can cause significant delays. Some versions of ogpsd 
have had significant problems in this respect. Make sure your time and 
timezone are set correctly as this can slow things down too.
