I just tried DRI with a radeon 7000 again and am still getting the
same old error message when inserting the radeon kernel module:

[drm] Initialized radeon 1.9.0 20020828 on minor 0
[drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held
[drm:radeon_unlock] *ERROR* Process 968 using kernel context 0

This is the same error message I saw on an x86 machine with a radeon
chip.  I don't think AGP is available after this error message, so
something must be different in your setup.  Can you confirm that you
didn't get the same kind of drm error when loading radeon.ko?
