How to maximize GPS battery life ?

if I want to use my FR as a GPS track logger (for an OSM mapping party
for example), what is the best way to save battery life ?
It seems that GPS chip is able to keep the fix while FR is suspended
(/sys/devices/platform/gta02-pm-gps.0/keep_on_in_suspend), but I need
the CPU to log data, don't I ?
Currently, I think I would do something like this :
- shut down GSM (FR is also my phone)
- launch fsoraw -r GPS tangogps and start logging
- let the FR disable display after 30s (problem : any touch on screen
will keep it up)
Any idea ?
