http://stuge.se/filo.r52.ide_ext2_pio4_debug6.patch accomplishes many
things. I would like to get them all into svn but I'm not sure what
the best approach is.

Three changes are rather safe and it would be nice if they got in
before 0.6:

* ide.c: Improve debugging
* ide.c: Add 32-bit PIO
* fsys_ext2fs.c: Add debugging and some error checking

Two changes are less safe, the first one more safe than the last. I
would like the first change in 0.6 too, but I think the last one can
wait until after 0.6.

* ide.c: Change await_ide() function and create AWAIT_IDE() macro to
  replace the function calls; slightly different semantics and much
  improved functionality
* ide.c/blockdev.c/fsys_ext2fs.c: Implement multiple sector reads

Of course, I also have some forward porting to do before anything
will get committed.. Thoughts?
