Does the LED support include displaying stuff like load and network activity on them?
Yes, you can use LED triggers as usual. (this works w/ any LED devices in the common LED subsystem).
Is there also a chance you have an optimized kernel config that doesn't build stuff the APU doesn't support anyways?
It's not absolutely minimal, but a good start for further trimming down (eg. remove filesystems you dont need, etc).
