playing with real-time on a regular system?

[Robert P. J. Day]

  short question:  can i add real-time support to a regular kernel
(rt.wiki.kernel.org) and use that kernel on a regular system, so that
the system continues to run (mostly) normally unless i want to start
experimenting with real-time features?  in short, i want to mess with
real-time but don't want to have to devote an entirely separate system
to it if i can avoid it.

  longer question:  if i can do the above, what's the best way to add
RT support to a fedora-flavoured kernel?  i can see from the current
fedora kernel source rpm (2.6.29.2-126) that there are numerous
patches applied to the stock kernel source, and it's probably a good
idea to hang onto them.

  so, normally, i'd download the latest kernel source rpm, "rpmbuild"
and install that manually.  however, for RT, i'd obviously want to
prep the kernel source and then (if possible) apply the RT patch, then
finish the build.

  i can see that there is a 2.6.29.2-rt11 patch, but it's obviously an
issue as to whether that patch will apply to the "fedora"ized kernel
source with all of the fedora patches applied.

  thoughts?  what's the best way to go about this?  thanks.
