I'll bet the default value of SHMMAX on your kernel is 1MB.
You said 6.4.x worked for you, right?
A stock version of 6.4.x creates a shared memory segment of about
830K if you don't alter the default -B setting. Thanks to some
changes I made recently in the memory space estimation stuff,
the current CVS sources will try to make a shm segment of about
1100K with the default -B and -N settings.
If 1MB is a popular SHMMAX default, it might be a good idea to
trim down the safety margin a little bit so we come out short of
1MB at the default settings ...
