Commit "switch cursors over to generic allocator"
(5b1978a4796bcc31ac2f01d303dc8f8f44323025) resulted in my laptop's built in
screen going black as soon as XOrg loads.

The machine is not locked up.  I can switch to VTs and enter commands, however,
the display remains black (even when switching VTs) until I reboot it.  Due to
the commit description, I tried the "SWcursor" option and discovered this does
not happen (i.e., it works) if it is specified.

I'll attach full logs for running with the previous commit and this one.  The
differences are (I may have caused an additional VT switch or something when
collecting the running blind log):
