 Thanks, I think knocked that one on the head when I removed the
 cpuscaling package. The module is available but not loaded, next kernel
 rebuild I will turn it off.

 Yes, took me a while to figure out how to get an 800x600 mode, X kept
 trying to correct me - annoying !
 The application is a full screen PAL video conference system, hard coded
 to 800x600 and requiring xv.

 I write a lot of one off embedded stuff, it would be nice to override a
 lot of the "X.org clever" with my very own stupid.
 I wish X.org had a command line like more like this :
 "X -ac -no*ingscreensaver_ever -onlythisres=800x600 -bpp 24 :0"

 I often want
         1) a listening tcp socket - I know the risks, its what I want !
         2) a fixed resolution in all cases on all hardware or an error
         3) no screen saver - ever ever ever
         4) no dynamic resize,scale,rotate - fixed fixed fixed !

 On applications not requiring xv I simply enable the kernel framebuffer
 in the kernel args and use a generic Xorg config for fbdev.

 The X display runs -ac with a remote camera system pushing CCTV images
 at it, while a second machine streams XV data into an area.  3 computers
 (4 if you count the pxe boot system) - one display. The network is
 private and local so good old raw X is fine.

 Uploaded just for you, video clip of my wife Waiman playing very badly.

 The CCTV images are much more intersting in the daylight.

 Cheers,
 Jon
