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 difficult 
to single step with interrupt pending. You end up in the interrupt. I have been 
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 should 
have put the patch out earlier.
