Oh, one other thing, you also need to tweak the vendors Makefile thusly:

$(ELFIMAGE): $(ROMFSIMG) $(LINUX)
        BSS=`$(CROSS)objdump --headers $(LINUX) | \
                grep "\.bss"` ; \
        ADDR=`set -- $${BSS} ; echo 0x$${5}` ; \
        $(CROSS)objcopy --add-section=.romfs=$(ROMFSIMG) \
                --adjust-section-vma=.romfs=$${ADDR} --no-adjust-warnings \
                --set-section-flags=.romfs=alloc,load,data   \
                $(LINUX) $(ELFIMAGE)

(it's right down the bottom of the Makefile - change the line

        ADDR=`set -- $${BSS} ; echo 0x$${4}` ; \

to be

        ADDR=`set -- $${BSS} ; echo 0x$${5}` ; \

this is in the latest patchset sent to snapgear, and should roll out
into CVS soonish.
