Also, if you're hex editing the ST.DB file, I'd recommend changing the name of the file to "pbl.xbe" (both instances). Personally, I think it's much nicer than "linux.x" (Linux? What Linux?). I suppose "exploit" is okay too (as above), but it doesn't show that it's an XBE file.
As a side note, one instance has been replaced with "exploit" in the above MIME-encoded file, while the other instance is "linux.x". It works though, and the instance of "linux.x" will be replaced by "exploit" when you run it for the first time.
