intel i810 Dell graphics

Try as I may with sax2, yast and /etc/xorg.conf I simply cannot get anything greater than 640x480 resolution. I hear that xorg 7.0 may be the solution. Meanwhile, google throws up few if any clues to grasp onto. _Will_ a Dell inspiron PIV with 512Mb give anything other than 640x480 with SuSE 10.0? Can anyone help us? Thanks, Steve.
