[linux-dvb] Module loading error

I am using the CVS version of the DVB drivers with FC4 (Nexus-s card) for
MythTV. After compiling the new drivers, I got some errors during insmod.
So, I went ahead and added modprobe.conf to my /etc/rc.local file in order
to load the module at startup (without this the dvb-ttpci module does not
get loaded at startup). But, I have some issues:

Here is my dmesg output:
<snip>

stv0299: Unknown symbol timeval_usec_diff
stv0299: Unknown symbol dvb_frontend_sleep_until
Linux video capture interface: v1.00
dvb_ttpci: Unknown symbol stv0299_writereg

DVB: registering frontend 0 (ST STV0299 DVB-S)...

Although the module is loaded, the device permissions seem to get reset
every time I reboot. As a result, I get a Cannot open DVB device -
Permission Denied error at the start of Myth backend. I have to change the
permissions of /dev/dvb/* manually with chmod, after which Myth is able to
open the DVB card.

Is there a better way to get the loaded correctly at startup with the
correct device permissions?

Thank you!
