Actually, the loading of this register is not needed. The original used
the loading to get the r2.
I actually wrote a fix for this a month ago. I never sent it out because
I was distracted by other issues.
I'll send out the two patches I had now.
Could yo test them?
Tested both the patches. Works fine.
Thanks
