Hi Goh
Since the .iso is in the root of sda1, the <path> is not actually needed.
I have tried many variations on this:-

menuentry 'PCLOS live iso' {
  loopback loop (hd0,1)/pclinuxos-lxde-2010.1.iso
  linux (loop)/isolinux/vmlinuz findiso=/pclinuxos-lxde-2010.1.iso 
boot=isolinux quiet  noeject noprompt
  initrd (loop)/isolinux/initrd.gz
}

I changed to boot=boot, livecd=livecd, boot=livecd and the result is 
always the same:-

ACPI: Aborted because no cpio magic.
Kernel panic - not syncing: No init found. Try passing init= option to 
kernel.

I tried adding noacpi but no change.

With the findiso= the initrd won't boot - without it it runs and gets as 
far as detecting all hardware, then searches all devices for the "loop 
image" by which I am guessing it means livecd.sqfs ?
I tried livecd=(loop)/livecd but no change.

I have only 1GB ram - just a thought.

Yes - I did say "Off topic" that is another issue. It happens if I try 
to use the motherboard SATA controllers (nforce3). I have no problems at 
all using a PCI Silicon Image SATA card with the grub.cfg I paste binned 
earlier. Forget that issue for now!
