    It appears that the Touchpad shares the USB ID of the Keyboard. Here is the relevant verbose output from lsusb:

    Hah, you nailed it!

    Absolutely outstanding work, I shall add this info to the Wiki right now. Many thanks!

    EDIT: Someone's already done the honours, so I'm just going to revel in the glory of a fully functioning laptop.

    If you can get a patch to the current Ubuntu source and attach it to the bug report, it is likely to get better attention. This could be reported upstream (Linux) but that will likely not make it into the Ubuntu kernel for awhile.

    I'll do that. This is the first time I've dabbed around with the linux source. I'm unfamiliar with the patch issuing process, but am willing to learn

    i think a diff on the source package is sufficient, but I am not all that familiar with it either.

    It doesn't work! fn + delete works but special keys like brightness control, eject button, volume controls, etc. still does not work in my Macbook Pro Penryn.

    I think you still need to install pommed... but this thread is about the touchpad not the keyboard.

    The new bcm5974 driver should resolve this issue: http://ubuntuforums.org/showthread.php?t=840040

    UPDATE: Several confirmed users of bcm5974 on penryn now, so the thread could be considered solved.
