XFree86 with SiS 5597

Hi, i'm having some problems with my video card... It's a SiS 5597, i've cofigurated it, and it is working well in 800x600 mode, but when I use it in the 1024x768 mode, there is some noise on screen, just a few lines, it's very boring... did Anyone else have this problem? or better, did Anyone else
