Have you tried smaller aperture sizes (uninorth_agp.aperture) and/or
radeon.test=1? (See commit 52f072cb084bbb460d3a4ae09f0b6efc3e7e8a8c)

Neither changes anything.

How small aperture sizes have you tried?

32M. With the old UMS driver 3D once worked fine ...

The purpose of radeon.test=1 isn't to change anything but to catch
problems transferring data between system memory bound via AGP GART and
video RAM. Does it pass for the whole AGP aperture?

AFAICT yes.  For the default 256M it printed "[drm] Tested GTT->VRAM and
VRAM->GTT copy for GTT offset" for every other offset from 0x201000
to 0xfe01000.
