Rolling Back an Update?

When running Snow Leopard, is it possible to roll back an update? I'm specifically thinking of the update to the trackpad software on my MBP that came along with a recent Software Update, and which has been causing the trackpad to behave very strangely ever since...

Restore from your TM backup prior to the update.

Good idea.... now all I've got to do is to figure out exactly what to restore! Is there a log that records what the updates modify?

if you have spare drive partition, consider cloning your system before you apply any updates as well, something that would then be bootable.

you can even clone to sparse disk image, depending on size, partitions, etc (not something I would like with use drives though) and have images of 10.6.3, updates, etc. exact bootable images you can do smart or full restores.

You don't need to know what was installed, just when. Restore the entire system from some time before you installed the update. Afterwards, keep bootable backups/clones so you can immediately reboot into the prior installation.
