Btw, howto control it via /dev/adb? Can you point me to a document
which explains that?

Write a byte 0x06 followed by the PMU packet (all in one write());
read back the PMU reply (all in one read()).

What exactly does 0x06 mean?

6 just means "send to PMU".  It is a Linux thing, nothing to do
with the PMU itself.

thought something like that.

Flash led? Isn't there some kind of
"bright-led" "5V,12V,24V" settings available? I mean I want to be able
to change the brightness.

You can't change brightness on a LED.  You can however make it blink,
say, a few hundred times per second, and change the duty-cycle.

Ok, that's what I meant.

Please point me to a FM about adb.

What is a FM?  And it has nothing to do with ADB.

Well, it's the last part of RTFM, so I was asking
for the "fine manual", the documentation to ADB/PMU. So I can
lookup the commands I need for setting the led on/off.
