Comment 67 for bug 337935

It seems like there's a lot of noise on this bug; for what it's worth, I'm only really interested in one of the things mentioned in #38 <https://bugs.launchpad.net/linux/+bug/337935/comments/38>, "Can't click and hold with thumb while dragging with another finger.". I have a MacBook 5,3; on Karmic I have this problem and in the Lucid alpha the pointer jumps around so much in the live CD (even when I'm not touching the trackpad) that I couldn't do an install.
