Hello,
Same issue here, have been looking to solve this for a while. Although my Macbook Pro is very recent (mid-October), the problem appeared after I installed Leopard, but not right away.
I log in, and the little login window "shakes" and you can hear a beep-beepbepbeep-beeeeeeeeeeeeeeep as if some keyboard input was repeated endlessly. It happens even sometimes after I do manage to log in (by frantically clicking on the "back" button with the mouse on the login window, sometimes it works, sometimes I have to put the machine to sleep...) Sadly, I cannot predict when it will happen, as it sometimes behave perfectly.
So it doesn't happen all the time, just about half the time, and I won't speculate on whether it is a hardware or software issue, it is too hard to assess at the moment, since I use many different peripherals in conjunction with the Macbook Pro, such as Bluetooth wireless mouse and keyboard from Apple, and external monitors (many). The problem happens sometimes when such peripherals are enabled and plugged, sometimes not, sometimes without them, sometimes not...

I will be posting on the Apple Discussion forums about this too.
Very frustrating.
:-(
Any feedback, ladies and gents?
Thank you
