No it doesn't.  It's pretty much just a straight port of the 5.0 patch.

I had experienced the problem with ending up in the ISR when single stepping
on my target.  I ended up manually disabling interrupts in the SR when
single stepping to work around the problem.  I didn't know what the problem
was.  Thanks!

Does this patch deal with the lack of the single step bit in the CSR
register on 
the 5407 ?

For reasons unknown the designers removed this bit. It makes it very
to single step with interrupt pending. You end up in the interrupt. I have
working with Mark Abbate <mabbate at videonics.com> and Motorola to come up
with a 
solution. It is not nice. I am yet to place this fix into the driver. If you

contact Mark he may have a patch that you can use.

This is one reason I have not updated the package but still not excuse. I
have put the patch out earlier.
