Do not really understand your question, (don't need penlinux, maybe 
hence your question, just boot using grub2) but here's my menuentry in 
grub2, should be self-explanatory.

menuentry "Iso - natty-b1" {
search --set -f /iso/kubuntu-11.04-beta1-desktop-amd64.iso
loopback loop /iso/kubuntu-11.04-beta1-desktop-amd64.iso
linux (loop)/casper/vmlinuz boot=casper 
iso-scan/filename=/iso/kubuntu-11.04-beta1-desktop-amd64.iso noeject 
noprompt
initrd (loop)/casper/initrd.lz
}

note: I put iso file in directory 'iso' on a (any) partition.
you can of course use the usual
search --no-floppy --fs-uuid --set xxxxxxxxxxxxxx

for grml and others which don't use casper, use boot=live and use 
findiso instead of iso-scan, but you can check this out by mount -o loop 
the iso file first and watch for initrd.lz vs initrd.gz which is more 
commonly used.

Also you can use 'persistent' in linux line with a partition labeled 
'casper-rw' to keep any changes (except kernel updates).
