I am connecting to my pi(s) via a prolific 2303 cable and I eventually see a login, but no linux boot messages - I seem to recall being able to see these messages in the past, but I'm not sure now. I even tried rebooting with out disconnecting the cable and sure enough, I see the reboot message and then nothing until the login message:
raspberrypi login: pi

Is it possible to see the boot messages in real time (I know I can see them in retrospect via dmesg)?
