There have been some recent discussions about that kind of touchpad.  
You might have to update from 5.2.1 to a more recent 5.3-beta in order 
to obtain improvements, but "man psm" under 5.3 mentions:

      bit 11 FORCETAP
             Some pad devices report as if the fourth button is pressed 
             the user `taps' the surface of the device (see CAVEATS).  
             flag will make the psm driver assume that the device 
behaves this
             way.  Without the flag, the driver will assume this 
behavior for
             ALPS GlidePoint models only.

      Many pad devices behave as if the first (left) button were pressed 
if the
      user `taps' the surface of the pad.  In contrast, some pad 
products, e.g.
      some versions of ALPS GlidePoint and Interlink VersaPad, treat the 
      ping action as fourth button events.

      It is reported that Interlink VersaPad requires both HOOKRESUME and
      INITAFTERSUSPEND flags in order to recover from suspended state.  
      flags are automatically set when VersaPad is detected by the psm 

Perhaps try setting:

hint.psm.0.flags="0x800" /boot/device.hints...and see whether that helps.

Likewise, there has been a fair number of improvements to ACPI power 
management support between 5.2.1 and 5.3; updating to a more recent 
version is likely to help.
