Change the number in the middle of the line to the new runlevel that you want your computer to start in by default.
I verified inittab and it was set to run level 3, I changed it to 5 and it would not boot. I wound up installing fc11 beta and it now boots to run level 5.
Not sure if a later patch in fc10 handles video or fc11, either way I now have an excuse to try fc11 beta.
