I have an IdeaPad G560 and it has a bunch of LEDs on the keyboard. I would like to use some of these. Where should I look for files controlling these? There's no led directory in /proc/acpi (where it was on my previous laptop, in the asus directory) or in /sys/class.

Check out a program called ledd. Lets you program blinking sequences and change them on the fly.

At least on my Poweredge 2500 server, the leds are controlled through the console driver.
