I'm still not sure what those 64-bit mappings are, but note the modes:
$ sudo pmap -x $(pidof console-kit-daemon) 2>&1 | grep 654

These 64MB blocks are anonymous mappings that are not readable *or*
writable. As such, they take up no actual memory in the kernel, and
should be ignored.
And these mappings account for the vast majority of the memory reported.
So I think you should ensure that you're excluding such mappings from
your analysis.
After deducting the null mappings from the memory usage, ck seems to be
using a much more reasonable 25MB. So I'm closing this report as
invalid.
** Changed in: consolekit (Ubuntu)
