Nice.

Just to make sure I got you right: You enable the "g-sensor" and get about 3.3V,
then you suspend and _while suspended_ you get 2.4V and 1.8V respectively?
What happens when you resume? Do you get back 3.3V? If this is the case you
probably don't set GPD12/13 (CS), GPG7 (CLK), GPG6 (MOSI) to 0 and GPG5 (MISO)
to pulldown during suspend and leak the voltage from the CPU. Can you please
make sure you set those pins during suspend!
