Read the README in the PATCHES directory.  This explains how to generate a
patch for your kernel.  And yes, you do need to patch the kernel.  The IOP
version was reved to 11, and the 2.4.2 kernel still has 0.9.1 Beta2 LVM
code, which is IOP 10, so the Beta5 tools will not work with it.

I'll just advise you to make sure your backup is current.  I haven't heard
of any problems with Beta5 yet, but it's better to be safe than lose your
data.  It is a beta relese you know.  ;)  Other than that, the migration
process *should* be smooth.  Let us know if you run into any problems.
