Quite a number is already in on trunk, but as the support for devices is

header files eat up a lot of space in svn and only a very few will 
actually get used.

Jeppe once had provided a nice mechanism to me but it never made it to 
trunk. From the last comment of Florian on the topic the door id open 
for implementing something that makes handling easier, but honestly I 
did not spend much time on this.

obstacles for you to get rid of the preinstalled bootloader that you 
will most likely have to face.

Contact me in that case, I have already been down that road and have a 
working solution. (see
