So, everything I'm reading here and at XDA is heavily oriented towards Odin. Some of us can't run Odin, for whatever reason. I just spent a lot of time with Heimdall over the last two days, systematically trashing my Fascinate, panicking, and then restoring things to factory. This howto is Linux oriented, as I don't have a working Windows installation, nor access to OS X, so users of those platforms just ignore the compiling/installing bit and snag the binaries from Heimdall
