When I installed the current update on 5/2 or so it stopped working. I did go back and boot the older kernel and it still works, not some bizarre hardware thing. After boot I have /dev/video0 as the ibmcam, but after first attempted use the device is gone. Since it worked in older kernels I rebooted and tried running it in an older VM (fc9) using USB passthru to KVM. That also didn't work.
