Unfortunately, in meego, snd-hrtimer doesn't exist. Only modules in snd-* are:

(Note support for Native Instruments' USB soundcards
/kernel/sound/usb/caiaq/snd-usb-caiaq.ko and Tascam US122
/kernel/sound/usb/usx2y/snd-usb-usx2y.ko )

In order to enable the high resolution timer for midi/audio, should I
add /lib/modules/2.6.33.5-24.1-netbook/kernel/sound/core/snd-hrtimer.ko
from fedora13 i686 and do a "sudo modproble snd-hrtimer" (or add
http://nielsmayer.com/dist-alsa.conf to /etc/modprobe.d )? Is there a
reason snd-hrtimer.ko is missing from Meego, or is it available
through some more standard method?

Meego shows hrtimers -- would it be a problem on meego to use another
via snd-hrtimer?
