It's a great contribution (we started a similar effort quite a while ago
but didn't get far due to lack of resources), and unfortunately getting
the 4.2.0 release out kept everyone so busy that you didn't actually get
feedback in time.
The same applies to the implementation of register setting.
We don't know yet when we can start on integrating this contribution,
but it's definitely very interesting to have it in the product.
Some issues need to be sorted out, e.g. the licensing conditions are not
really compatible with what we accept as contributions, see
Thanks a lot for helping to improve VirtualBox!
