Comment 168 for bug 556782

I just had time to try this latest patch.
Unfortunately it does not correct the issue.
Is there any way to check or change the beginning and ending addresses of
sideport memory and stolen system memory once the system is up?
If there are registers I can read or write to experiment I will be happy to
try it,but I am afraid I was unable to comprehend a lot of the register
documentation from AMD.
