Less file system overhead on the flash side and no memory used to manage the structures needed to insmod / rmmod. Regardless, I would guess that the overhead is quite minimal. I believe some of the cheap n ath9k routers have their mtd partitions set up with a fixed space for the kernel, and would benefit from having their required modules in that partition.
