fixes behavior

Users of the SM plugin should not be allowed to start if the dlm isn't loaded. 


Patch adds a simple check for RHEL4 which checks for the existence of the
/dev/dlm-control device file upon startup.  This patch only applies to RHEL4 -
and should not be applied to the STABLE branch, since not all distributions
require/use udev.  For STABLE, this is a WONTFIX.
