Indeed. Freescale says they are working on this.

It's the other way round, i. e. the wiretap does not support Linux.

You can decode the backtrace maually from the System.map file, or you
can use our backtrace script for this purpose:
ftp://ftp.denx.de/pub/tools/backtrace

But in the end you will want to have a BDI200 anyway ;-)
