the modified bit set were written back (that's the case when they weren't put into
the modified pages queue yet), they were enqueued into the active queue twice, messing
up the page lists with various effects - this little thing took me busy for the last

* Improved the "page" debugger command: it now prints out much more info, and also lets
you lookup pages via physical address.
* The dump commands are now using kprintf() instead of dprintf().
