I just tried the latest mwebster-andy kernel from
http://moko.mwester.net/dl.html#kernels which has the sdcard clock
patches, and now i get even better signals, and fix from cold start
outside in 48secs.
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.
Cheers, and thanks for the good work!
