I'd recommend using a newer one.  You can get the current version from
<URL:http://cvsweb.netbsd.org/bsdweb.cgi/~checkout~/
 syssrc/sys/arch/arm26/stand/BBBB/BBBB>
(once the cvsweb server catches up with cvs.netbsd.org -- till then try
BBBB,fd1 instead).

That memory layout looks as if you tried to run BBBB from a running RISC
OS system.  Owing to the way the BBBB loads the kernel, it works best if
started from a Supervisor prompt on a fresh boot.  Start up the system
holding down keypad-* and maybe shift if you've got it configured to
autoboot.  Alternativly *Configure Language 0 and *Configure NoBoot.

For an explanation of BBBB's memory map, see

This error message is caused by a bug in the code that reports that the
memory layout isn't as BBBB would like it.

The prospect of starting BBBB in a taskwindow fills me with horror.  That
doesn't mean that it shouldn't work, but I don't think it will yet.
