Ok I was able to "fix" one by just unplugging it and replugging it. But
the 18lvx stays dead. Also the windows program to update firmware
doesn't detect it at all.
Maybe something is wrong with the fixed one as I don't have these files:
	/sys/devices/virtual/pps/pps0/{assert,clear}
I Do have 
	belle:/usr/src/ntp-dev-4.2.5p158# cat /sys/class/pps/pps0/{assert,clear}
	0.000000000#0
	0.000000000#0
but as you can see no pulse comes in. I explicitly switched it on:
	echo -e '$PGRMC,,,,,,,,,,,,2\r\n' > /dev/gps1
Kernel is 2.6.34.
	belle:/usr/src/ntp-dev-4.2.5p158# grep PPS /boot/config-2.6.34 
	# PPS support
	CONFIG_PPS=y
	# CONFIG_PPS_DEBUG is not set
	# PPS clients support
	CONFIG_PPS_CLIENT_KTIMER=m
	CONFIG_PPS_CLIENT_LDISC=y
and ldattach is running:
root     21949     1  0 14:46 ?        00:00:00 ldattach 18 /dev/ttyS1
