Not really.  I just know that the default rules in 59-dasd.rules don't have the 
equivalent of
ACTION=="add", ENV{COLLECT_0.0.0150}=="0", ATTR{[ccw/0.0.0150]online}="1"
in the file.  The /init script in the initrd _should_ pick up everything 
specified on the kernel command line, but there has been at least one bug in 
parsing that which has affected DASD units.  Doing it via udev rules means 
that's less likely to happen, and there's no need to rebuild the initrd.
