[jans2@jaki jans2]$ /sbin/lsmod | grep lsm
[jans2@jaki jans2]$ find /lib/modules/2.6.11-0.3.rdt.rhfc3.ccrma/ | grep
lsm
[jans2@jaki jans2]$

(i.o.w.: nothing 'lsm module' like is loaded by the kernel or found in
the modules directory...)

However:

[jans2@jaki jans2]$ /sbin/lsmod | grep realtime
realtime                5256  0
commoncap               7040  1 realtime

(read on about soundcard ...)

My soundcard: C-Media Electronics Inc CM738
Driver:       snd-cmipci
