The device files in /dev/dvb are created by the dvb subsystem after successful
initialization. So if module loading fails as you describe above, you won't have
the devices.
Your problem still is the mismatching module versions.
Could it be that you have the saa7134.ko module twice in the /lib/modules tree?
You need to use the new versions of the modules. *Don't* try to mix them.
