Just to keep the mailing list in the loop: We discussed this offlist a
bit and turns out it's a little bit tricky as some sections (systemid
especially) have a weird length (not a power of two). This makes the
whole handling a bit weird and we're probably not gonna gain any
performance here anyway.

So this is something to maybe revisit later.

The hex-part is still valid though, will fix that for the next version!
