I've done tests using dd to and from the raw block device under 2.4 and
2.6. Memory size (kernel boot param mem=) doesn't seem to affect
performance, so I assume that means that dd to and from the raw block
device is unbuffered. When I compare read and write speeds between 2.4
and 2.6, 2.6 is definately slower. The last 2.6 kernel I tried this
with is 2.6.5.
