Me neither.
Perhaps try something like (obviously untested):

cciss!.* root:disk 0660 @/lib/mdev/exclamat_subdir
ida!.* root:disk 0660 @/lib/mdev/exclamat_subdir
rd!.* root:disk 0660 @/lib/mdev/exclamat_subdir

$ cat /lib/mdev/exclamat_subdir
#!/bin/sh

# Move device to a subdirectory.
# If no subdirectory is given as argument to this script then
# use the device up to the exclamation char ('!') as directory.

if test "x$1" = "x"
then
  dir=$(echo "$MDEV" | sed -e 's,!.*,,g' -e 's,.*/,,g')
else
  dir="$1"
fi
test -d /dev/$dir || mkdir /dev/$dir

dev=$(echo "$MDEV" | sed -e 's,!,/,g')
mv $dev /dev/$dir/

We should start to collect some of these (after testing) in
examples/mdev/{lib/,mdev.disk.conf}, i suppose.
