Hmm...  interesting page -- but I see some entries that are
definitely different from the machine I have, including:

* NVIDIA graphics in my machine is a "Quadro M1200" (vs. "Quadro M2200")
* Wireless NIC is a Qualcomm Atheros part (vs. Intel(R) Dual Band
  Wireless-AC 8265")

I'm confused: why would you refer to "ALPS GlidePoint" as "outdated"?
The laptop I'm currently usng (the M4800) seems to probe the trackpad
thus, and it has been working fine.  Its predecessor (a Dell Precision
M4400) had similar hardware, with which I never had a problem,; I
strongly suspect that it was probed similarly.  Likewise for the M4400's
predecessors....

Thanks for responding, though! :-)
