I think you're right for the moment.  The TLB instructions are 
different between the two variants though; maybe there's some other
stuff?

I guess the bootloader needs to force the W bit to 0?  I note that on
an interruption, the W bit is set to the value of the default width
bit, but how to set the default width bit is implementation defined. 
Anyone care to hint at how to set the default width bit too?
