Please make sure that your user is not a member of the "disk" group. Try running "groups" to check, and "ls -l /dev/hda".
Yes, that was the misconfiguration I talked about, I've changed that now. But still I would say that this is a bug since wine+Diablo 2 really shouldn't be trying to mess with your MBR to begin with.
