GPS stopped working, can't figure it out... what else?

[Yaroslav Halchenko]

funny enough, on SHR unstable
1. I have no /dev/gps (ok, added symlink to ttySAC1)
2. om gps power 1
   puke with 'no file' since

   access("/sys/class/i2c-adapter/i2c-0/0-0073/pcf50633-regltr.7/neo1973-pm-gps.0", F_OK) = -1 ENOENT (No such file or directory)

   and doesn't seems to try

   /sys/devices/platform/s3c2440-i2c/i2c-0/0-0073/pcf50633-regltr.7/regulator/regulator.7/gta02-pm-gps.0-RF_3V/power_on

   I guess, om is not that freerunner/SHR compatible atm? ;)

in any case... if I just do everything manually I get nothing:

root at om-gta02 /dev # echo 0 > /sys/devices/platform/s3c2440-i2c/i2c-0/0-0073/pcf50633-regltr.7/regulator/regulator.7/gta02-pm-gps.0-RF_3V/power_on
