I'm sorry, I was busy and then forgot the issue. I've tried with breezy's GRUB
(0.95+cvs20040624-17ubuntu7) and get a slightly different behaviour: I still get a back screen after boot but after a time (the 10 s timeout? I've not tried to lengenth it to confirm) it boot the default OS. Something strange is that the keyboard isn't recognized by GRUB: hitting enter or the up/down arrows don't change anything: it wait and then boot after about 10s whatever I do on the keyboad.
