Alright. I just did a small test run.
[yagi2 at nova7 ~]$ rpm -q kmod-drbd
package kmod-drbd is not installed
[yagi2 at nova7 ~]$ uname -a
Linux nova7 2.6.18-92.1.13.el5 #1 SMP Wed Sep 24 19:32:05 EDT 2008
x86_64 x86_64 x86_64 GNU/Linux
[yagi2 at nova7 ~]$ rpm -q kernel
<So, the system does not have kmod-drbd and has kernel 2.6.18-92.1.13.>
[root at nova7 ~]# yum install kmod-drbd
Package Arch Version Repository Size
kmod-drbd x86_64 8.0.13-2 extras 794 k
Install 1 Package(s)
Update 0 Package(s)
Remove 0 Package(s)
Total download size: 794 k
Is this ok [y/N]: y
<kmod-drbd has been installed on the system successfully>
[yagi2 at nova7 ~]$ ls -l `find /lib/modules/ -name drbd.ko`

<The above result is what I expected>
