It is the only possible way. Right before going to sleep, write down the
timestamp and the battery capacity. Right after waking up, write down the 
timestamp and the battery capacity. Compare the results with and without 
ehci_hcd. For my T43 (2669), it makes a difference of more than 0.5Wh 
(which is a lot, considering that s2r draws about 260mWh).
