You can get the list sizes more easily:

nassau:~$ grep active /proc/vmstat
nr_inactive_anon 267
nr_active_anon 392461
nr_inactive_file 258286
nr_active_file 416048

Or even more detailed from /proc/zoneinfo, as each memory zone has its own set of lists.

The inactive > active rule is only enforced during reclaim, we don't mind the list sizes on idle systems.
