Is it possible that the init-sequence from XP differs, which permits
the led to turn on?

Possible.
AFAIK Registers 0x1006 and 0x1007 contain the GPIOs for the LEDs.

So maybe you should try to get the value for 0x1007, too.

I made some primitive filters with grep - so if you want to save
yourself some time - just record the log and mail it to me.

Hello,
I mailed it to you as gz archive. I tried some combinations of 1007
and 1006 but without success, the video-stream  got even broken.

I'm not sure whether you ever got my mail so here it goes again:

Here's your result:
    00000000: 80 80
  Value                   = 00001006
--
    00000000: 00 00
  Value                   = 00001006
--
    00000000: 80 80
  Value                   = 00001006
--
    00000000: c0
  Value                   = 00001007

  Value                   = 00001007
    00000000: a0
  Value                   = 00001006
--
    00000000: e0
  Value                   = 00001007
    00000000: 80
  Value                   = 00001006
--
    00000000: c0
  Value                   = 00001006


As you can see the final values are:
0x1006 - 0xc0
0x1007 - 0xe0

Please try to apply these values to your cam via debugfs and tell us whether it is working.
