[CentOS] touchpad problem

Hi all!

I have a new-to-me (i.e., used) laptop and am having a problem making
the touchpad behave.

It is an old HP Elitebook 8530p, and I THINK it has a synaptics
touchpad. But I don't remember how to get more specifics than that
on Linux, lspci, lsusb and lshw don't tell me anything helpful.
lsmod doesn't list anything containing "syn" or "synaptics".

Anyway, I've installed C7 on the laptop and pretty much everything
works just as I expect it to, but even though I configure the touchpad
for two-finger-scrolling, it simply won't do it. It also won't do
edge-scrolling, and it has a mark along the right side of the pad that
seemingly implies it should do edge-scrolling.

If I could figure out which synaptics touchpad it is I might be
able to find out if it does or does not support two-finger scrolling
(like both my netbooks do).

Can any of you remind me how to find out the Synaptics model it is,
and/or figure out if it would be expected (or not) to support two-
finger scrolling?

Any advice will be appreciated, thanks in advance!

Fred
