Based on what I see on your /etc/fstab I have supposed that the / directory is /dev/sda1 : is that right ? It's not /dev/sda6 that is probably the partition where /home is ?
Based on this supposition, here is a menu.lst:
timeout 10
color black/cyan yellow/cyan
gfxmenu (hd0,0)/boot/gfxmenu
default 0
title linux
root (hd0,0)
kernel /boot/vmlinuz BOOT_IMAGE=linux root=/dev/sda1 resume=/dev/sda5 splash=noquiet vga=788
initrd /boot/initrd.img
title linux-nonfb
kernel (hd0,0)/boot/vmlinuz BOOT_IMAGE=linux-nonfb root=/dev/sda1 resume=/dev/sda5
initrd (hd0,0)/boot/initrd.img
title failsafe

For the kernels I didn't change anything, because I need the content of /boot directory and mini to know in what kernel dir you have the kernel modules.
What is changed is "root=/dev/sda1" instead of uuid, same for resume.
If this still does not work, try to change "sda1" for "hda1". If this still doesn't work check the kernels (as said just above).
If nothing works I don't have solution left for you apart from reinstall.
