Android only eats 256mA?

...it certainly claims so...

I'm pretty sure it eats 500mA and there's a bug to be fixed... Also. Just taking 500mA from USB is not nice, as some USB ports (Sharp Zaurus) can only suuply 200mA or so... (Is there some kind of bugzilla where I should file this? Or just complain on IRC?)
