FC2: Audit errors on /var/log/messages (SELinux (?) newbie)



Hello again, 

A while ago I asked help for my odd xkb/mouse problems after doing FC1 ->
FC2 update. Now everything seems to be pretty ok, but I get a lot of audit
error messages. Now, I know I should try to figure it out myself, but I
could use some advice about where to look to get these things fixed (audit
is new to me, I assume it has something to do with selinux?). Below is a
bit of messages log created during the boot. 

There is quite a lot of those audit avc: denied messages in the log. Any
pointers? A good tutorial, howto or any other means to quickly get this
fixed? 

There were some discussion about /initrd left mounted or some such? Will
it be the cause of this problem? I have no idea of what is going on here
.. Is it possible to turn SELinux off or something? 

Thanks in advance!
