Valuable to try to build a *small* kernel?

It seems to me that the "small kernel thing" really had to do with the 512 
KB limit
imposed by the loader.  This was dealt with by compressing the image, then by
modularizing a lot of drivers.  For all I know they've got loaders to 
handle it now.
But 2-5 MB for a kernel in 256 MB of memory isn't much of a dent.
Maybe worry about ram buffers that these drivers allocate?
