Wait, you didn't say that there was an "EFI warning" when you posted this
to the debian-sparc mailing list. And there shouldn't be one as the machine
uses OpenFirmware plus GPT for the partitions tables.

I forced to install GRUB on /dev/sda, finally the installation finished without 
any error...but failed to boot with "Can't open boot device".

You need to bind-mount /dev, /proc and /sys into the chroot before
that command works:

# mount -o bind /dev /target/dev
# mount -o bind /proc /target/proc
# mount -o bind /sys /target/sys

Those above error messages are also a result of the missing bind mounts.
