This has nothing to do with DRI. The system locks up for me when kdm
shows its login screen, or shortly thereafter.

I'll try nevertheless. I'll also try a config with DRI disabled.

It might be related to some changes with PCI mapping, as both

- 6.8.2 Xserver + backported CVS radeon driver
and
- CVS Xserver + 6.8.2 radeon driver

worked fine (both with minimal patches, syntactical and symbol
exporting).
