	Ahh, you mean the patches provided at 
<ftp://ftp.udel.edu/pub/ntp/software/nanokernel.tar.gz>?  Those are 
for Linux only, and are only applicable to older versions of the 
Linux kernel (2.4.x and before).  If you were going to run Linux, 
then these would be appropriate to be considered.

	Note that FreeBSD doesn't need any such kernel modifications, as 
the necessary features have been built-in for quite some time.  The 
availability of these features for FreeBSD, Linux, Solaris, Tru64, 
etc... are discussed on the page you mentioned.

	However, I don't know if the same features are available in 
NetBSD or OpenBSD.

	Indeed, if you're looking for high resolution time service on 
UltraSPARC, your options with regards to the OS are going to be 
extremely limited.
