Ok, after some discussion on IRC, and invaluable help by Sven in documenting
smartfirmware behaviour, I came up with this patch.

Please let me know what you think.  If there are no objections I'll check it
in in a few days.

        * include/grub/ieee1275/ieee1275.h (grub_ieee1275_flag): Add
        GRUB_IEEE1275_FLAG_EFIKA_SECRET_AVAILABLE_REGION flag.
        * kern/powerpc/ieee1275/cmain.c (grub_ieee1275_find_options): Set
        GRUB_IEEE1275_FLAG_EFIKA_SECRET_AVAILABLE_REGION flag when running
        on an Efika (SmartFirmware).
        * kern/powerpc/ieee1275/init.c (grub_claim_heap): Fail gracefuly when
        addr > heaplimit.
        Use grub_printf instead of grub_error for error reporting, since
        grub_error doesn't work at this point of execution.
        When GRUB_IEEE1275_FLAG_EFIKA_SECRET_AVAILABLE_REGION was set,
        release hardcoded 0x4000:0xffc000 region.
