Wasn't there something that added the DM_* variables to the kernel
directly? I remember seing something a while back. If that is still
planned or possible, maybe you can just do thes both rules only if the
values are not set?
ENV{DM_NAME}="", ENV{DM_NAME}="$attr{dm/name}", ...
ENV{DM_NAME}="", IMPORT{program}= ...

NAME="$kernel" is the default, it's not needed.
