Still hoping for an answer, as the PC locked up hard a few more times,
always when trying to exit the X server (normal logout/all clients
terminated, ctl-alt-bs, init 6).  The PC is a Dell Optiplex 740.  Its
onboard video is NVidia NVS 210S nVidia GForce 6150, but that is
disabled when an add-in video card is present (wasn't present in the
'pciconf -lv' I posted last week).

What can I do to determine whether the X11 problem is
"bus_dmamem_alloc failed to align memory properly" or something
else with the card?

thanks,
Jeff
