Hard to explain, the EC (Embedded Controller) touches mouse/kbd HW large parts 
of ACPI code make use of the EC(e.g. reading out temp, battery,...). The EC is 
a separated microcontroller with its own firmware, so don't ask why/where 
exactly the interference happens, it just happens, especially on the HPs which 
(as far as I can tell) seem to have broken EC firmware.

This is really weird. Better recheck your .config file with previous ones...

The patches that should fix up most mouse interference problems on HPs can be 
found here: bug #7689. Latest kernels should already have them included, but 
you might want to double check, that your's also has...

Can you please also attach a full dmesg output (Have you experienced any 
AE_TIME errors in /var/log/messages?).
