ok Now I'm confused.  First you say get rid of mode lines then you say to 
generate some using cvt.  To be clear 1280x1024 is what I want to use, and 
what I was using with the old via chipset.  The problem is that there is 
horrible flickering (with parts of the screen that shouldn't be there 
being interleaved in )that makes the screen unusable at that resolution 
and I have to use 1280x800, and with that the bottom of my kde bar is cut 
off.  Getting rid of the modelines didn't seem to help anything.

   I have discovered that I can use the vesa driver at 1152x864 with no 
flickering and see the whole screen, so that is what I am using for now.
I tried openchrome at 1152x864 but still got the flickering, as I did with 
vesa at 1280x1024
