Description of problem:

By default 'mdadm' is installed and its startup service turned on.
This results in the following message every time a machine is started

Starting mdmpd: Kernel md module does not support events
                                                           [FAILED]

This message is rather misleading.  That modules possibly does
support events but it does not exist.

How about abusing a modprobe a bit and adding close to the top
of /etc/rc.d/init.d/mdmpd something like that:

modprobe --show-depends md >/dev/null 2>&1 || exit 0

Hm, that would prevent mdmpd from running also for a custom
kernel with md support "built-in"; but maybe then its existence
can be checked by other means (through '/proc/mdstat')?
Or I am mistaken here and mdmpd attempts to do something
which it cannot?  md driver is reported in dmesg:

md: md driver 0.90.0 MAX_MD_DEVS=256, MD_SB_DISKS=27
md: Autodetecting RAID arrays.
md: autorun ...
md: ... autorun DONE.

If the action is infeasible then why /etc/rc.d/init.d/mdmpd
is not bailing out silently?
