I must be missing something...the above should branch
to: sr7.0xc008dbc0, not to "0xc008dbc0".  I.e., you specified SR7
in the BE instruction, so it gets used.  

Of course, if you'd said:  
   BE,N 3c0(0,r1) 
the result would effectively be the same (because it's a short
address, we grab the upper two bits of $c008dbc0, add 4, and therefore
use SR7 as the space register).

So, SR7 indeed needs to be set correctly...but since I haven't
looked at the surrounding code...
