It seems there were lzma patches for cramfs floating around, but all the
websites have vanished. Even archive.org did not give the code I was
looking for. Some code which seems to have served as a base for the
cramfs lzma patches is archived, but I don't know in what state it is.
Then there's the CE Linux Forum. They might still have one of the patches
