So are you able to test what happens when you unload the driver?

As I wrote in previous email, I do not own these EliteBooks anymore,
so cannot test it. Just have DSDT dump...

What about contacting last contributors to hp_accel.c driver? They
probably could test i801 changes if accelerometer still works.

Good idea.

Added Martin and Dominique who did the last additions to that driver
(hp_accel.c).

Do you guys still have your HP machines around? If yes, maybe you can
try v4.7-rc3+ (it should include commit a7ae81952cda ("i2c: i801: Allow
ACPI SystemIO OpRegion to conflict with PCI BAR")) so that you unload
i2c-i801.ko and see if accelerometer still works?

I still have the HP ProBook 440 G3. I used v4.7-rc7 for the test. I
tested all combinations of loading/unloading both hp_accel and
i2c_i801 modules and whenever the hp_accel was loaded the
accelerometer worked fine.
