XVM: This binary works on both 6.5.22 (on a IP30) and 6.5.29 (on a IP35)

1. Verify you have xvm installed, install from overlays, if necessary. You may also want to install sysadm_xvm to get a GUI.
% showprods eoe.sw.xvm
I = Installed, R = Removed

   Name                 Date        Description

I  eoe                  01/18/2009  IRIX Execution Environment, 6.5.29
I  eoe.sw               01/18/2009  IRIX Execution Environment Software
I  eoe.sw.xvm           01/18/2009  XVM, Volume Manager

2. Make a backup of the original and copy in cracked version
# cp /sbin/xvminit /sbin/xvminit.orig
# cp xvminit_6.5.22-29.cracked /sbin/xvminit

3. Run xvminit
# xvminit $yourhostname

4. Verify 
# xvm show -subsystem
