Just to clarify, VT switch or desktop switch?

Are you sure you were using fglrx?  AFAIK, fglrx never supported your chip.
You need to use xrandr to enable/disable outputs.  You need to
configure your hotkeys toe generate events and then tie those events
to xrandr if you want to use the hotkeys.  Beyond that, are you saying
the LCD panel on your laptop isn't working or just problems with VGA?
You should open a bug (https://bugs.freedesktop.org) and clearly state
what the problem is and attach your xorg log and config.
