[PATCH] sg driver against lk 2.5.25

This patch is against lk 2.5.25 . It
  - fixes copy_from/to_user() [William Stinson from dj tree]
  - disables kiobuf use, so it will compile without kiobufs

The latter change is so Andrew Morton can remove kiobufs
as suggested in his "direct-to-BIO for O_DIRECT" thread.
