Here is what I did:

1)  Installed openSUSE-11.0.
2)  Used YaST2->"Software Repositories" to add 
http://download.opensuse.org/repositories/home:andavis/openSUSE_11.0
3)  Used YaST2->"Software Management" to install dazuko-2.3.6 and dazuko 
2.3.6-kmp-pae
4)  Started dazuko with "/etc/init.d/boot.dazuko start"
5)  lsmod shows the dazuko and redirfs modules are loaded
6)  Downloaded AntiVir personal
7)  Installed AntiVir personal using the its install script
8)  The installation gave three options for avguard:  1) have avguard 
load dazuko, 2) have avguard assume dazuko is already loaded, 3) don't 
install avguard.  I selected option 2.
9)  The installation proceeded w/o errors and antivir and avguard started.
10)  /etc/init.d/avguard status shows that it is running.

Please let me know how this differs from your configuration.  Did you 
select to have avguard load dazuko?

Thx,
