I'm afraid this might be a different problem which should be fixed by
commit 93225b0d7bc030f4a93165347a65893685822d70 ('drm/radeon/kms: forbid
big bo allocation (fdo 31708) v3'). Might be worth making sure that
commit is applied for all your tests.

Though I guess the bus error might still be related, even if the buffer
eviction succeeds...

Is there any known good kernel at this time? 2.6.36?
