If you look at:

you can easilly check that the work seems splitted in 5 points.
Let's say that #5 should be addressed by recent kib@'s work about
fdclone (for a better overwiev please look at:

The state of other tasks is a little bit floating.
For example, pmap_mapdev_attr() and pmap_change_attr() are fully
working on FreeBSD-i386, but currently support for large pages is
missing. These should be addressed through superpages work, so I
strongly suggest you to check with alc@ about them and to ping him
about his further superpages plans.

In the end, maybe you should concentrate mainly about #2 and #4.
As evicted by private discussions with Christian Zander, nVidia
doesn't really have preference for the KPI, so you can choose what you
feel more appropriate, according with kib and alc (CC'ed).

Good luck,
