Let's start by simplyfying that diff by throwing out all the cruft from the
Config.lb file:

--- Config-lab.lb	2008-11-26 14:29:06.000000000 -0500
+++ Config.lb	2008-12-02 23:18:42.000000000 -0500

 romimage "fallback" 
 	option USE_FALLBACK_IMAGE=1

-	option CONFIG_PRECOMPRESSED_PAYLOAD=1
-	option ROM_IMAGE_SIZE=0x17000
-	option XIP_ROM_SIZE=0x40000
+	option ROM_IMAGE_SIZE=0x20000
+	option XIP_ROM_SIZE=0x20000
 	option COREBOOT_EXTRA_VERSION="$(shell cat ../../VERSION)_Fallback"
-	payload ../payload.elf.lzma
+	payload ../payload.elf
 end
 
-buildrom ./coreboot.rom ROM_SIZE "fallback"
+buildrom ./coreboot.rom ROM_SIZE "normal" "fallback"

So basically these are the differences:

1) no normal image in the lzma case, only fallback
2) some size parameter differences
3) payload filename is different

Thanks,
Ward.
