Intel 810? Do you have an onboard video card?
If so, do you also have an nVidia video card? If not, these drivers won't work at all for you (you need nVidia hardware, and AFAIK the Intel onboard video is definitely not nVidia)...
I'm thinking, however, that you had an Intel onboard graphics chip when you installed RH the first time, then either disabled it or installed the nVidia card without disabling it. If that's the case, disable the onboard graphics from your BIOS setup screens, and comment out the 810-related stuff in XF86Config (it's not needed anymore).
Otherwise, a reinstall would (probably) fix it, and if you do install with the nVidia card in there, it won't put anything i810-related in the config file to begin with.
