There's no 1.50 kernel plugin for the newest firmware?
It would be good to have a version that worked on newer kernels,
but it would be hard to pull out all the 1.50 kernel stuff now.
It makes use of the LEDS, IR port, serial port, etc. as well as other
1.50 kernel specific modules and code snippets.
For this one I've been aware of the changes to make from the beginning,
so I can get it working on new firmware fairly easily to have a go with the USB GPS.
