I am looking at doing base jobs to help avoid tying up systems for too long though until multi-threading for the FD arrives it's kind of moot as it takes the same amount of time with large file sets.    I use the MD5 checks as a means to verify file integrity and to restore if a file gets corrupted.   

To get around the issue I set the MD5 at a full backup window and then have written a couple small shell scripts that are multi-threaded/process to check the files on the systems every week (checks run in less than 18 hours opposed to the 9-10 days if I ran a verify w/ bacula).   I then can compare those md5's with the ones in the catalogue and restore just the corrupted files.

So I take it that there is no way to do this except a manual process at this point?

I am running v5.0.2 against some clients with many files (5-10

to do a md5 check when I do differentials/incremental's due to the fact 
that it takes days for bacula to calculate the md5's as it's single 
threaded.
Why do you want the md5 checks when doing a full backup?  Are you using Base
jobs?  If not, then the full backup doesn't check the md5 anyway because it
always backs up every file.
