There shouldn't be any major differences.  Once the device is opened, the
VFS layer will direct any read or write syscalls pretty much directly to
those functions.

Do you actually have a /dev/null or do you delete it once by accident and
now just have a regular file in its place?  Do a "ls -l /dev/null".
Should look like:

  % ls -l /dev/null
  crw-rw-rw-   1 root     root       1,   3 Dec 31  1979 /dev/null

I can't reproduce your drive flickering under either 2.0 or 2.1.
