I made some little steps.

I've installed grub on my usb flash using qemu:
"qemu -kernel bzimage -hda=/dev/sdc"
where sdc is my usb flash.
It tries to boot, but it stops.
I figured out that it tries to boot the bzImage on RAM (and it's larger 
than my memory).

So I've deleted the output/ folder, made some modifications and rebuilt 
all obtaining a smaller kernel and a smaller fs.
Now it boot, but always using the bzImage (I've only /boot/grub/* and 
bzImage on my flash usb). Every modifications does not survive to reboot.

So I've built the vmlinux image and tar fs, but I got
"Grub Error 13: Invalid or unsupported executable format"

There is a way to use a vmlinux image and the fs directly on the flash 
drive?

Thanks
