The really good news is that as of Linux kernel 2.6.38, which is the 
default in the upcoming ubuntu 11.4 release, hardpps() has become a 
standard part of the kernel, just as on FreeBSD. :-)

Also like FreeBSD, it seems like you have to enable this in a kernel 
config file and recompile, but you should no longer have to patch the 
kernel first!
