tried dosfsck(8)?  it once fixed nearly precisely the same situation for
me (invalid fs on a camera CF card).  i used it against the original media
IIRC after taking the exact same kind of diskimage you had (in case dosfsck
broke the media-bound-image further).

for me it came with a package called 'dostools' in redhat 7.2, but i bet
you can find its original home on google or rpmfind/apt-cache search =)
