As I wrote already, there is a bug in kernel GPS suspend/resume code which leads to GPS not being powered after resume. Simply re-enable it manually via Settings, or apply my patch sent to kernel list (but still not merged into git) - http://lists.openmoko.org/pipermail/openmoko-kernel/2009-January/007447.html I'm attaching also a version against stable.git for those still running 2.6.24..

Fix re-enabling of GPS on resume
The call to gps_pwron_set(0) during suspend would clear power_was_on
flag so the on/off status was always lost
