You are working at the correct level. The bgwriter performs the I/O smoothing
function at the database level. Obviously, the OS level smoothing function
needed to be tuned and you have done that within the parameters of the OS.
You may want to bring this up on the Linux kernel lists and see if they have
any ideas.

Will do so, this seems to be a reasonable idea.
