The UUID on the 'search' line should be that of the partition on the CF
card which holds the kernel and the initrd. The line can omitted, as can
the 'set root' line. The 'linux' and 'initrd' lines are required.
/vmlinuz-2.6.32-5-686 root=LABEL=CFCARD ro
tells GRUB it will find a file vmlinuz-2.6.32-5-686 on the card in the
root of a partition which has the label 'CFCARD'. Is such a file there?
And has the partition been labelled ('tune2fs -L' is one method)?

Let's see what GRUB knows about the partition with label CFCARD. Boot
and go to a command line with 'c'. Any sign of it in the output of
'ls -l'? Alternatively, what does 'search --label CFCARD' say?
