That was my mistake, I forgot about AGP vs PCI on radeon. Should be
fixed in next release:

Hi ,

If you are sure that the HW worked fine before. I think you should:

1. Be sure that HW works fine now.
2. recall the driver to the point at where it works well, and then replace them 
one by one to confirm component which causes the issue.
3. try to update the last VBIOS to adapt new driver.

Thanks

Well, that is rather old hardware. I suggest to make sure first that the
hw isn't broken in some way.

You first need to figure out what's the failing component. Either Mesa,
DDX or the Kernel are possible candidates.

Another possibility is that you updated kodi and kodi is now doing
something the hw doesn't like.

Christian.
