Re: RH 2.6 64-bit experience needed

They are patch files.  You apply them with the 'patch' command.
For example:
  Create the link from /usr/src/linux to /usr/src/kernels/xxx
  as I described in the previous e-mail.
  cd /usr/src
  tar -xvf LiS-2.18.0.tgz
  cd /usr/src/LiS-2.18
  patch -g0 -p1 < LiS-2.18.0-A.patch
  patch -g0 -p1 < LiS-2.18.0-B.patch
  patch -g0 -p1 < LiS-2.18.0-C.patch
  make
    for sles9 say 'n' to the third prompt and enter the correct path
      Do you intend to run LiS on this machine with
      the currently running kernel? [default: y]
    use defaults for all other prompts
  make install

The A,B,C does imply the order in which they should be applied.
For x86_64 you should look at the LiS-2.18.0-C.patch file and
note the compile and link flags used for that platform.  That
information comes from /usr/src/linux/arch/x86_64/Makefile
