I've also been trying to get binding to work, I got the tool compiled (I used libusb-compat-0.1-0.1.8, MSYS on windows), I can dump cards but I can't get them to boot properly. Binding boot after 'decrypting' it using the the magic hex key at offset 0x28 doesn't result in the same key after re-binding it. I'm really starting to wonder if the version of ps3mca that can be found is complete. Can someone verify that they got this to work using the zip labeled jimmikaelkael-ps3mca-tool-12a198f, it has sha1 hash of B5315A5530D051E130D83D966CFD2E06F207170B.
