Are you sure that will build against a stock Debian 2.6.17-1-686 kernel?
I get errors with module-assistant saying that support for realtime-lsm
as a kernel module is not supported by the current kernel.
I've guessed that I need to set:
CONFIG_SECURITY_CAPABILITIES=m
(setting for stock 2.6.17-1-686 is CONFIG_SECURITY_CAPABILITIES=y)
and build a custom kernel, boot into it then run module-assistant to
build the realtime-lsm module?
Yes, you are correct; I'd forgotten about that part as I've been using
that config for a while.
Here's a link to a how-to on the Agnula site which includes use of the
realtime module and the necessary config.

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.
Arthur.
After applying the fixes to /usr/src/modules/realtime-lsm/realcap.c
listed above, I found the easiest way to make a realtime-lsm package
that installed was to do:
cd /usr/src/linux-source-2.6.17
make-kpkg modules-image
cd ..
dpkg -i realtime-lsm-module-2.6.17_0.1.1-6+2.6.17-10.00.Custom_i386.deb
After rebooting, I have module realtime loaded, and was able to start
jackd and run muse, playing a complex MIDI file to the hardware synth on
my SoundBlaster Live! 5.1 Digital model SB0220 sound card cleanly whilst
extracting the 2.6.17 kernel source to disk.
Hope this helps someone.
