Remove the LZMA compressed payload and adding the payload manually
(uncompressed) and rewriting the image, the GRUB payload is started
without problems.

        $ build/cbfstool build/coreboot.rom remove -n fallback/payload
        $ build/cbfstool build/coreboot.rom add-payload -n fallback/payload -f grub2.elf
        $ build/cbfstool build/coreboot.rom print
        coreboot.rom: 4096 kB, bootblocksize 1008, romsize 4194304, offset 0x0
        alignment: 64 bytes
        Name                           Offset     Type         Size
        cmos_layout.bin                0x0        cmos_layout  1776
        pci1002,9802.rom               0x740      optionrom    65536
        fallback/romstage              0x10780    stage        347052
        fallback/coreboot_ram          0x65380    stage        205897
        fallback/payload               0x97840    payload      576263
        (empty)                        0x124380   null         2996248

So I would claim, the payload is functional.
