K18
  taken from 2.6.18 kernel.org, modified for HP.  It's mostly the
  same as K08 with the pci* changes that were done.  RHEL 5.1 and
  5.2 were compiled with this source and tested thusly.

K18-RHEL5-Xen
  taken from RHEL5.5 source with some backports that solve race
  conditions at rmmod time (unregistering IRQs).  These conditions
  have not been apparent before now,but something in the Xen kernel
  exposes them on rmmod ipmi_si.  This source should be safe for all
  2.6.18 and above kernels, if not then use the K18 source.

  The ProLiant OEM channel changes are also here, along with some
  constants that don't appear in linux/ipmi*.h prior to the
  RHEL 5.5 backport.

As an aside, in Feb 2010 I don't know what happened with RHEL 5.3.

To build:
1. cd to the appropriate directory
2. make -C /lib/modules/`uname -r`/build M=$PWD modules
