I think It would be a nice thing to have a native Linux SLIC driver.
For FXS it may be easier than to implement DECT and other things that
the firmware does support.
Does the SLIC support the DECT functionality or is it somewhere else?

I have never detected the VPE specific command line at AVM
Fritz!Boxes. Do you know how they do it?
The Easybox 904 uses the same VPE approach by loading the firmware,
reduce system memory and so on. But this one is a bit more simplified.
