You'll actually want to increase min_free_kbytes in order to have the same
amount of memory free as 2.6.8 did.

Start by applying my patch and using the default min_free_kbytes. Then 
increase
it until the page allocation failures stop, and let us know what the end 
result
was.

BTW we should probably have a message in the page allocation failure path
to tell people to try increasing /proc/sys/vm/min_free_kbytes...
