So I just read this

and it looks encouraging.  Apparently NetBSD is using it.  Does anyone
know if they are happy with it?

They are relatively happy with it... 
 
Has FreeBSD considered this?

Yes, but it would be a huge porting effort.
 
Has anyone benchmarked FreeBSD against NetBSD to see which is faster
for VM stuff?

Generally, the benchmarks favor FreeBSD. Again, it's a cleaner design, but the time spent optimizing FreeBSD's and eliminating the bottle necks has paid off...
