I've built a kernel with

CONFIG_SECURITY_CAPABILITIES=m

but module-assistant complains (see Debian bug #366552 for realtime-lsm)

which references

http://www.uwsg.iu.edu/hypermail/linux/kernel/0410.1/0248.html

I've applied the fix, built the realtime.ko file and worked around 
module-assistant complaining that the build failed by manually putting 
realtime.ko into 
/lib/modules/rebuilt-kernel-version/updates/realtime-lsm and ran:

 depmod rebuilt-kernel-version

I have yet to test it all.

The current process is broken and has already been reported against 
package realtime-lsm.
