It works when switching before and after the suspension.

sysctl hw.syscons.sc_no_suspend_vtswitch was 0 for the non-working
case.  Setting it to 1 does not do quite the right thing.  After
waking uk to first shows an intact X11 screen but then switches to a
blankc screen with a cursor, then to just a blank screen.  Afterwards
you can Control-Alt-F9 into the X11 server, but only if you
Control-Alt-F8ed into a text tty first.

Anyway, since I can run a second X11 server for the case that I need
DRI and don't have to shut down my main one that is actually pretty
close to a satisfactory solution.

Now to getting suspend-to-disk working.  I guess i shouldn't just have
allocated all disk space to FreeBSD so easily :-)
