So the voltage patch certainly helped, and the sdcard clock patches seemed to have made it even better. I have not tried accessing maps from sdcard while using GPS, but i will try and test that later.

Is it in a daily build? FWIW i just flashed http://buildhost.openmoko.org/daily/freerunner/200807/20080715/uImage-om-gta02-latest.bin today and i got a fix outside with my sd card inserted.

I do this using the utility at http://svn.openmoko.org/developers/matt_hsu/agps-online/ Using my account details and current location i can get agps data loaded, but it still makes no difference for me getting a fix if the sd card is still in place.
