I am using kgdb, the in-kernel debugger, to debug kernel modules. 
The debugging UI running in the dev machine is gdb, while kgbd in the target presumably implements a subset of the gdbserver. kgdb only supports an UART link connection as of today.
Once everything is set, the debugging process is just identical to that of regular app debugging, and the ability to use nemiver instead of gdb would be a *major* improvement for any kgdb user.

Unfortunately, kernel or kernel module debugging requires to pass some funky commands to set things up. Worse, some of the kgdb / gdb peculiarities are such that the sequence of commands are not always constant.
I haven't found a way to access a "gdb console" inside of nemiver, allowing me to manually drive gdb, for things like 
- resetting the UART, 
- executing a gdb command file (source gdb command), 
- executing add-symbol-file command,
- doing an up then down sequence to initially sync the code at the breakpoint with the source, 
etc... 

Or is there already a way to enter commands commands to the gdb below nemiver that  I missed?)

If such a thing is not currently possible, could it be added to the enhancements list?
I would be soooooooooo happy to use nemiver instead of that poor old crappy ddd that's so painful to use and so poorly integrated into gnome!
