No. SysV shared memory is part of the "System V IPC" option, and it
can't be compiled as a kernel module. All kernels provided by
distributions have this enabled, AFAIK. 

What is the value of /proc/sys/kernel/shmmax ? Try to set this to a
large value (like 32MB) with:

  echo 33554432 > /proc/sys/kernel/shmmax

If you compiled your own kernel, be sure that you enabled SysV IPC.
