Chainloading Grub into Clover or any EFI executable

Hello guys,
I've been working on an hackintosh of mine (with GPT) and I'm having a small problem;
I've installed Clover in my ESP partition but when I try to chainload it with Grub I'm having an "unexpected error". I'll post this evening anything useful that come in my mind.
Does anyone have a similar problem?

Re: Chainloading Grub into Clover or any EFI executable

Actually, I removed my Clover installation from my ESP.
Some info:

My GRUB2 custom code:

cat /etc/grub.d/40_custom
#!/bin/sh
exec tail -n +3 $0
...

menuentry 'Mac OS X' --class osx --class darwin --class os {
	insmod fat
	insmod hfsplus
	insmod part_gpt 
	set root='hd0,gpt10'
	search --no-floppy --set=root /usr/standalone/i386/boot.efi
	chainloader (${root})/usr/standalone/i386/boot.efi -v
}

...

Result of all (before removing Clover)

My main problem, as for now, is to chainload Clover or something similar in GRUB. Is it possible?
