another stupid question from my side:
do
bb.data.getVar('foo', d, 1)
and
d.getVar('foo', 1)
access the same data?
Thanks in advance
Andreas

It does but the later is supported on recent bitbake versions only.

This is wrong. It's been supported since the first checkin of
data_smart.py in 2005. We just used the other one as a potential
separation of public api and private implementation. We have since
changed our minds and realized that we could just as easily replace
the object with something else which conforms to this API.

Yes.
The first is calling the class method and passing in an instance of a
data object, the second is calling the method on the object directly.
Either way you're using the same data object, d.
The latter is more pythonic and we've been slowly moving the code
towards that style.
Also for stylistic reasons please use True/False rather than 1/0 for the
final parameter.
Cheers,
Joshua

Should be and later is preferred AFAIK, see:
