Brendan,
Canon's mighty Digital Photo Professional is the software that comes with your camera to open RAW files. Why aren't you using that?
The garbage you're seeing in Adobe Camera RAW is Adobe trying to reverse engineer the Canon RAW specification. Along with botching the colours, it's also going ahead and trying to rectify defects in the image.
Canon's DPP is the /only/ true Canon RAW format converter, as far as I'm concerned. Everything else is a hack.
