Why would the OS affect the battery life while the machine is suspended?
The CPU is shut off while asleep, and things are controlled by the laptop's embedded controller. If the Eee PC drains half its battery overnight while suspended, that is likely to be true of whatever OS you install on it.
Assuming that it isn't a an unfixable hardware bug, this is the sort of thing a BIOS upgrade would be likely to fix.
