Now I can confirm the Bochs crash when running DxDiag (tested with 
Win95B and DirectX 6.1). It was possibly caused by the non-VGA screen 
update handling that was still present in 2.6.9. DxDiag probes the 
Voodoo device by switching it on and off and and this seemed to cause an 
undefined behaviour. This no longer happens with current SVN, since the 
screen update and mode switching stuff has been rewritten.

Thanks,
Volker
