I'm afraid the only candidate place for this to be applied would be
sid, not in a stable release.

OK, please let us know.

There's no doubt that if this device is to be supported it should be
via DT.
But if the kernel image is too big for this device then it may not be a
device which we can support at all.

OK.
I may be confused regarding which of the two systems mentioned have
issues with the size of the kernel supported by the firmware.
If you can figure out why the LS-WTGL doesn't work and that can be
fixed (i.e. it turns out to be something other than the size) then I
see no problem with adding support for the LS-WTGL platform.
Ian.
