I hope someone wins the debate soon and gets this to work and be "user
friendly".  I'm about to make a fresh backup and try this again.  I have
upgraded my kernel to a really new version, 2.6.25.  Sorry, nvidia won't
compile with anything newer that I have tried. 

If it don't work this time, this could end up a with permanent -hal for
xorg-server.  I quite happy with the way my box works now anyway.  ;-) 
Just trying to keep up with the times I guess.
