There are two things - the extended resolution and general timing handling.

The extendend resolution would be done providing the API. But there is 
quite some work
to make the APIs fullfull the expectations. For that we would need to go 
into
the tickless direction and use precicion (one-) time interrupts for timeout
and timing handling. That would be a more elaborate project. FreeBSD is
using the precision time interrupts for a while now, if I looked 
correctly into
the kernel code.
But, I am too busy now for such a project.
