Oh haha, good point. Depending on the build, USB storage might not be working. I haven't ran a CM9 rom in ages on the KF, but you will have to enable USB storage in order to see it as the SD card on the PC. Otherwise, I would honestly just run the Hashcode CM10 rom available on XDA. It's a pretty good experience, and he has made kernel improvements that give me significantly better battery life than we ever got on ICS. I have had a few issues with the device not coming out of sleep, but it's nothing a reset doesn't fix...just hold the power button for 20-30 seconds like you typically would.
