I assume you're referring to the Wheezy package, not the Grml package.

What conf file? /etc/default/grub??

Did you see your isos being added to the grub.cfg?

At what point during the booting of the isos from beneath /home, in an
lvm, is the lvm accessible? ;-)

I haven't used grub-imageboot for a while (since it was a Grml package)
but... when I did, I had the iso images beneath /boot on an USBKey using
FAT32. I had problems with other filesystems[*1]
Posting grub.cfg might be instructive. grub-imageboot doesn't use a
loopback system to extract the kernel and initrd, which makes it
difficult to figure out what's going on (it maps iso directly into memory).
Note that memdisk ISO emulation is tricky[*2] - some images will use it,
others require different versions (or memtest), or simply won't work.
I'd suggest you use a simple USBkey setup to try and isolate your problem.
I found grub-imageboot to be more trouble than it's worth for booting
Linux systems. Great for non-Linux systems though....
