Look in the repo for a kernel with rt-preempt in its name string.

Alternatively download the source tarball from the kernel.org site, 
install build-essential, and build your own.  Make a hard copy of an lsmod 
report, and using "make xconfig", disable most of what is shown as a 
default module build (a period is shown in the checkbox, clear the box by 
clicking on it) leaving only what is shown on the lsmod listing, then near 
the top of this seemingly unlimited choices of characteristics, check on 
the stuff needed to make it an rt-preemptable build, including in the 
makefiles extra version entry so it will be made with that now unique 
name.  rt-preempt seems like a good name to add.

as you, make clean;make;make modules;
sudo make headers-install
sudo make modules-install
sudo make install
sudo update-grub (or grub-update, I furgit)

Watch the output of this to verify that it found your newly installed 
kernel.  If it did, then reboot to it and test it.  If the attempted boot 
fails, write down the failure msg, reboot to the original kernel, run make 
xconfig again and see if you can find, from what you wrote down, whats 
missing and re-enable it.

Repeat the above make loop till it works.

TANSTAAFL:* Bear in mind that running such an entirely performance 
configured kernel you will probably need a cooler fan equipt parking place 
for your lappy, and its use can reduce the life of a battery charge to as 
little as 25% of what it gets with the kernel that was originally 
installed, so I would always plug its psu/charger in when being booted to 
this high performance kernel.

*TANSTAAFL, from E. Hemingway, popularized by R.A. Heinlein, for "There 
Ain't No Such Thing As A Free Lunch"

I have a script I use for the build/install that I can post if there is 
any interest.
