grub2 efi + lvm hangs after loading initrd

[lideony]

Hi 

I already spent a lot of time but I can't get grub2 to work. I used the latest grub version from svn and compiled and created the grub image like described here: http://grub.enbug.org/TestingOnEFI. I placed the image and modules on my efi partition and select grub.efi from the refit menu.

Mac OS X boots fine with grub2 but I can't get linux to boot. I use lvm on my boot and root volume on a macbook pro 5,1 and have the following problem: 

After selecting linux in the grub2 menu I get the following output:

Booting a command list
[Linux-bzImage, set=0x3200,size=0x1f918]
[Initrd, addr=0x4fd6f004, size]

I've read that other people have the same problem when they use lvm...

This is my grub.cfg

timeout=10

menuentry "Mac OSX 10.6" {

  root=(hd0,2)

  chainloader /usr/standalone/i386/boot.efi

}

menuentry "Arch Linux" {

        insmod lvm

        fakebios

        root=(vg0-boot)

        linux /vmlinuz26 root=/dev/mapper/vg0-root noefi video=efifb agp=off

        initrd /kernel26.img

} 

When creating the grub-mkimage I used these modules:

ata part_gpt part_msdos fat ntfs ntfscomp ext2 iso9660 udf hfsplus fshelp reboot normal chain linux xnu xnu_uuid ls search search_fs_file search_fs_uuid search_label help loopback cat tar boot configfile cpio sh echo lvm loadbios efi_gop multiboot multiboot2 relocator

Any help would be appreciated!
