 After killing the 'gdb' session, starting X normally worked properly.
 Similarly to PR xsrc/50599, the r128 driver and/or X server claim only
 to see a DVI output when the card has none.  Nevertheless, it proceeds
 to recover EDID data and a plethora of modes, allegedly from the monitor.
 It reports DDC capability, but claims the DDC read attempt failed.  The
 only mode it will choose by default is 2048x1536x85 which is out of
 range of any monitor I have.  (The CRT it is presently using will do
 2048x1536x60 and an LCD I tested it with will only do 1440x900x75,
 1440x900x60 and smaller, but the driver always picks 2048x1536x85.)
 Therefore, a minimal "xorg.conf" is needed with a Monitor section to
 describe the timings and available modes and a Screen section using that
 monitor with a Display subsection to list the preferred modes.
 Will try again with the custom kernel with "r128drm* at drm?", although
 that may wait until the latest update to -current is finished building.
