Stefan did that as diploma thesis in our department at IBM. The ugly
part was the swap file handling. The swap files had to be saved after a
dump in order to access all user space memory. We added the save
function in lcrash:
lcrash -S <swapdump>
to generate a dump-file containing all used swapped out pages of all
swap areas.
And we added an extra parameter <swapdump> when starting lcrash to
analyze the dump:
lcrash map.x dump.x kerntypes.x <swapdump>
Here the posting on the lkcd mailing list:

But the code was never integrated officially in lcrash.
