  FWIW, I have also seen seemingly identical symptoms a couple times on
a Debian server I set up a couple weeks ago at work, also using a
Radeon card (Radeon 9250) and xorg.  The console goes away (freezes
completely), Control-Alt-Backspace doesn't work to restore it, but the
system is still accessible via ssh.  This leads me to suspect the
reported problem may not be a FreeBSD issue per se but an xorg Radeon
driver issue.  Reducing the maximum sync setting may have helped, but I
don't consider it confirmed yet.
