Nice article Harry! Some remarks though:
* Is /dev/rtc the kernel timer? I thought it was the device node for
access to the real-time clock. I don't even think it's necessary to
prioritize it anymore because most applications use the kernel timer:

I'm far from an expert on timers so I could be wrong, I still find this
a bit of esoteric stuff.
* Using setpci in this context is deprecated unless you're still using
am machine with a PCI bus which I highly doubt:

Also, when pasting output from commands use a
"pastebin" like
http://pastebin.com/ and provide a link, it makes for
easier reading.
I'd like to take this back: its better to have the information neatly
available on the mailing list.
If I find some time, I'll write a quick post
on tuning an Arch system for
maximum low-lat RT performance.
Link to article, (note it is geared towards Arch linux, but the same
concepts apply across distro flavours)

Thanks for providing the incentive to write this article, -Harry
