Thanks a lot Ducan, for all the info.
You helped me eliminate several variables.
AGP still won't work, but I'll just see how far I get with PCI(E) mode
I'm now always forcing KMS by using radeon.modeset=1

Looking at the demsg, the following two errors seem to prevent X from loading
the r600 module:

This (1)
 [drm] Forcing AGP to PCIE mode
[   17.311865] radeon 0000:01:00.0: PCI: Disallowing DAC for device
[   17.311867] radeon: No suitable DMA available.

and this (2)
[drm:radeon_ttm_backend_bind] *ERROR* failed to bind 1 pages at 0x00000000
[   17.485886] radeon 0000:01:00.0: object_init failed for (4096, 0x00000002)
[   17.485889] radeon 0000:01:00.0: (-12) create WB bo failed
[   17.485892] radeon 0000:01:00.0: disabling GPU acceleration
[   17.502518] radeon 0000:01:00.0: f7229e00 unpin not necessary

any ideas, how to fix these?
