Thanks for the suggestion about checking for a directory.  But how will I 
determine what version of LVM if it's a directory?  Will there be 
/proc/lvm/version?

As for the checking for the module file.  With the way module management is 
being changed in recent kernels I'm not about to do such checking as it's too 
likely that things will get broken.

I'll just assume that if the LVM module isn't loaded then the administrator 
doesn't want it to start.

LVM isn't something that you want to be automatically loading on demand, 
either you need it or you don't.  If you need it then you will probably want 
to compile it in or put it in /etc/modules for loading on boot.

Done.
