Hello to everyone in the list!

I now have jack capabiilities in FC2!

Here's what I did on my FC2 laptop with original

1) Downloaded kernel-2-6-6 from kernel.org and also downloaded
the 2.6.6-mm3 patch.
2) If this is terrible please tell me, I made a /home/kernel
directory, and     
    extracted the new kernel there.
    tar -jxvf linux-2.6.6.tar.bz2
* The steps 3 - 7 were a total failure
3) Applied the 2.6.6-mm3 patch: 
    patch -t -p0 -i 2.6.6-mm3
4) Copied /boot/config-2.6.5-1.358 to .config
5) make oldconfig
6) make xconfig (just to see if there were any other options),
now this 
    presented me with the qt dialog, but it had no characters I
    recognize, like the charset was completely fsck'ed up... so
    discarded it.
7) make bzImage
8) Bunch of errors!
* Ok start over...
9) I made a backup of the patched kernel to another directory: 
    mv linux-2.6.6 linux-2.6.6.patched
10) Did 2, 4, 5 again
11) Made xconfig but the same problem appeared so dumped it.
11a) Edited the makefile and added my initials to the version
number just for testing dtc00
12) make bzImage && make modules (almost an hour later
everything built)
13) sudo make modules_install && sudo make install
14) No problem, rebooted with my fingers crossed and everything
went just fine!
15) Started jack: error message a suitable kernel should print
... (no capabilities).
16) cd  to where I downloaded a the realtime patch
17) make KERNEL_DIR=/home/kernel/linux-2.6.6 (Fail!)
18) Just for curiosity sake went to the 
http://jackit.sourceforge.net/docs/faq.php site to see if there
were any news. No, everything looked just the same, but I went
to: http://sourceforge.net/projects/realtime-lsm/ to see if
there was a new version, and yes there's
19) Downloaded it and built with:
      make KERNEL_DIR=/home/kernel/linux-2.6.6 (Success!)
      sudo make KERNEL_DIR=/home/kernel/linux-2.6.6 install
20) System map rebuilt
     sudo /sbin/depmod -ae -F
/home/kernel/linux-2.6.6/System.map  2.6.6-dtc_00
     sudo /sbin/modprobe realtime allcaps=1 (Success)
21) jackstart now printed no errors just the usage instructions.
so it seems to be working. Now try hydrogen, but first start
22) jackstart -R -d alsa -d hw -n 3 -p -z &
      back from read, ret = 1 errno == Success
jackd 0.98.0

24) Loads of joy and happiness when my funky-demo started up
sounding awesome!

I hope this helps! (just to prove that FC2 is not a total audio
failure)  :)
