You could change this driver so that it supports one DIMM. Move the
'hotplug' part into another driver which creates and destroys
instances of the hwmon DIMM device as the DIMMS come and go.
Also, do you need to handle CPU hotplug? You could split the CPU
temperature part into a separate hwmon driver? And again create and
destroy devices as CPUs come and go?
