Well, I found the first issue at least: the neogps app uses an old path
to power on the gps device.
I changed this now, but until a new build arrives, use this script
(compatible with 2.6.24 and >=2.6.28):

if [ -e /sys/bus/platform/devices/neo1973-pm-gps.0 ]; then
  echo 1 > /sys/bus/platform/devices/neo1973-pm-gps.0/power_on
# for older kernels
if [ -e /sys/class/i2c-adapter/i2c-0/0-0073/neo1973-pm-gps.0/pwron ];
  echo 1 > /sys/class/i2c-adapter/i2c-0/0-0073/neo1973-pm-gps.0/pwron
Do an "echo 0" to power it down after usage.

Also, I've seen a bug report go by that tells me there's an issue with
gps and 2.6.28 kernels in that you can't reenable the gps after
unsuspend, so you might want to try without suspending as well.
