I can confirm the presence of the "radeon_dma.c:210: radeonRefillCurrentDmaRegion: Assertion `dma_bo->bo->cref == 1' failed.' assertion on a stock Karmic installation (32 bit, Dell Dimension 3100, Radeon 7000/VR100).

I have installed Mesa 7.8 and the accompanying libdrm from todays xorg-edgers PPA, and it does indeed rectify the issue.
 mesa 7.8.0~git20100210.f88b43e8-0ubuntu0sarvatt~karmic
 libdrm 2.4.17+git20100210.4f0f8717-0ubuntu0sarvatt~karmic

Some random datapoints:
% glxinfo |grep rendere
OpenGL renderer string: Mesa DRI R100 (RV100 5159) 20090101 x86/MMX/SSE2 NO-TCL
% lspci|grep VGA
03:02.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]

Problem and workaround verified with both an older and a current copy of googleearth.
