Keep XBMC running without HDMI?

[skok]

Hope this isn't a dupe, but I couldn't find it.

My setup RPi-(hdmi)->receiver-(hdmi)->tv

When I turn off/standby my TV, the receiver also goes off via CEC, which is the wanted behaviour. Problem is, in that scenario the RPi loses it's monitor, which results in XBMC exiting - at least there are only login-prompts on ^C{2-12}. So when I power on the tv and thus the receiver again, I also need to restart XBMC as an X11 process or completly reset the RPi.

That's of course quite ugly, but for powersaving reasons I'd like to have a proper solution to this. Is there any?
