Definitely if the driver is allocating an RTEMS message queue.
You have to account for it.

CONFIGURE_MAXIMUM_MESSAGE_QUEUES

and you need to account for the message buffer memory.  In 4.7
and older, you use CONFIGURE_MEMORY_OVERHEAD
which is the number of extra KB (not bytes) you want for message
buffers.

In CVS, I added CONFIGURE_MESSAGE_BUFFER_MEMORY
to account for this.  When a CVS RTEMS, you shouldn't have
to use CONFIGURE_MEMORY_OVERHEAD unless something
is broken in confdefs.h or you are just being sloppy guessing on
message buffers and task stacks.
