It works just fine on my Asus L3500H, with or without ACPI.

I've recently started work on getting psm to support Synaptics TouchPads more
fully: virtual scrollbars, up/down buttons, multiple finger detection, etc.  I
have the basics working, but my brain has been too fried lately to deal with
the maths of translating absolute coordinates to sensibly accelerated motions.

Which Synaptics TouchPad do you have?  Does psm say anything useful when you
tell it to be verbose?

  A man should be greater than some of his parts.
