That got it, though for some reason lspci listed the busid as 0:11:0 and the xfree86 log listed it as 0:17:0. 0:17:0 worked.
Now for the next issue, if I try and use different resolutions the 17" lcd Borks (fuzzy display 640x480 resolution.) The refresh rates are good.
If necessary I can live with it, but the 1280x1024 on the 17" LCD would be nice.
My Horizontal Sync Rate was off. I have it all working now! Yay!!!
