 Steps to reproduce:
 1) boot andy-tracking 5a6ed99264c704e5 with Rask's cpufreq patches
 (http://iki.fi/lindi/openmoko/consumption/cpufreq-*.patch)
 2) sudo sh -c "echo 1 > /sys/class/i2c-
 adapter/i2c-0/0-0073/pcf50633-regltr.7/neo1973-pm-gps.0/power_on"
 3) gpsd -F gpsd.sock -N -n -D 1 /dev/ttySAC1
 4) ctrl-c
 5) sudo sh -c "echo 0 > /sys/class/i2c-
 adapter/i2c-0/0-0073/pcf50633-regltr.7/neo1973-pm-gps.0/power_on"
 6) sudo sh -c "echo mem > /sys/power/state"
 7) wake the phone by pressing power button
 8) sudo sh -c "echo 1 > /sys/class/i2c-
 adapter/i2c-0/0-0073/pcf50633-regltr.7/neo1973-pm-gps.0/power_on"
 9) gpsd -F gpsd.sock -N -n -D 1 /dev/ttySAC1

 Expected results:
 3 & 9) gpsd reads gps data over serial port correctly.

 Actual results:
 3) gpsd reads gps data over serial port correctly:

 gpsd: garmin_gps Linux USB module not active.
 gpsd: => Probing device subtype 0
 gpsd: Satellite data no good (1 of 1).
 gpsd: => Probing device subtype 1
 gpsd: => Probing device subtype 2
 gpsd: => Probing device subtype 3

 gpsd: Satellite data no good (1 of 1).
 gpsd: Satellite data no good (1 of 1).
 gpsd: Satellite data no good (1 of 1).
 gpsd: Satellite data no good (1 of 1).
 ...

 9) gpsd prints only

 gpsd: garmin_gps Linux USB module not active.

 and kernel floods the logs with
