The only kernel parameters I know of that relate to X is setting
CONFIG_MTRR to y if your CPU supports MTRR.

It looks like the config is correct.  The default depth should be
selecting 1024x768.  If you are starting X via startx or xdm/gdm/kdm,
you should have a .xsesssion-errors file if there is anything wrong.

You could try removing the 800x600 and 640x480 resolutions and see what
happens, but I won't guarantee what will happen if 1024x768 fails.  It
will probably simply abort.  Do you have enough video memory to run that
resolution at 24bpp?

If your chip can support DRI, it should be included by default in X. 
Look in /var/log/XFree86.0.log and look for Direct Rendering enabled.
