Okay, we can reproduce it. 

IMPORT and $env were introduced into udev around the time of 05x udev
releases, while CentOS 4 still is at 039 (and likely will stay there). 

So yes, the udev rules won't work. 

I'm at the moment preparing the last rounds of the drbd-8.3 rpms for
CentOS 4 and 5 and will remove the udev rules for CentOS 4 in that rpm.
