I switched back to my old syntax and added an entry for 'sdX' devices, 
restarted clvmd on both nodes and every seems to be fine now! Here is my 
latest, working, filter line:

filter = [ "a|drbd.*|", "a|sd.*|", "r|.*|" ]

Thanks for the help! I'll be looking forward to testing out the fix in 
CentOS 5.5. :)
