 typo error? should be elftuls-0.118-1, right?

I always download the latest source codes from CVS and then make 
systemtap. Or you can just use the latest snapshot of systemtap source 
codes. The later, the fewer bugs.

I ran on RHEL(U2 & U3). I never tried FC4.

It will do. Remember to modify the scsi.stp to change 
module("scsi_mod").function("foo") to kernel.function("foo")

If you have the kernel src rpm package, then you can:
  1. rpm -Uvh kernel-src-.rpm
  2. vi /usr/src/redhat/SPECS/kernel-2.6.spec, uncomment unnecessary 
options, e.g:

  %define buildup 0
  %define buildsmp 1
  %define buildsource 0
  %define buildhugemem 0
  %define buildlargesmp 0
  %define builddoc 0
  %define kabi 1

  3. You may need modify /usr/src/redhat/SPECS/kernel-2.6.spec 
because of the bug 
#1966(http://sourceware.org/bugzilla/show_bug.cgi?id=1966)
  4. rpmbuild -ba /usr/src/redhat/SPECS/kernel-2.6.spec --target=i686
  5. look at /usr/src/redhat/RPMS for the devel, debuginfo and kernel 
rpm package

If you compile the kernel using mainline kernel src package for 
kernel.org, you should:
  1. enable "compile debuginfo for kernel" & "kprobe" when "make 
menuconfig"
  2. make & install the kernel
  3. cp /usr/src/linux-2.6.15/vmlinux  /boot/vmlinux-2.5.16
