Ok..I am familiar with xorgconfig and xorgsetup for autopolling or manually setting your display and stuff. The question I have is..

LABEL cubez
MENU LABEL BT3 Graphics mode (Compiz Nvidia) - Experimental
KERNEL /boot/vmlinuz
APPEND vga=0x317 initrd=/boot/initrd.gz ramdisk_size=6666 root=/dev/ram0 rw chexpand=256 load=cubez,nvidiadriver autoexec=xconf;startnvidia.sh;startx

The underlined area would be my point of interest. Is there a way to get you xconf file and save it to recall in this file. If that is possible, where would you store that file so the syslinux.cfg file knows how to recall it.
