Is there a resource for CentOS for things to do before a hard reboot?

My situation is apparently an out of memory condition where I am seeing fatal 'oops' output all over the place, Ctrl-Alt-F3 (for example) new console login attempts will accept credentials and then never get to a login prompt. Remoting in is just as useless. I cannot therefore use any of the standard restart commands, since I cannot enter commands.

By default in CentOs (and on my machine) Alt- SysRq is disabled.

Do I have any other options before hard resetting the box?

Thanks,
