Hiten's patchset for section four manpages, slightly edited by me.

Update man pages in the section 4 to match the reality in -CURRENT.

- Change lines referring to kernel configuration file:
device foo0 at isa port xxx irq yyy...
to
device foo
Describe resource "hints" in /boot/device.hints.

- Try to describe resource allocation and probe/attach behavior in the
newbus framework.

Prepare for mdoc(7)NG.

mdoc(7) police: use the new features of the Nm macro.

remove fullstops from the end of .Xr lines in SEE ALSO sections.

Use Fx macro wherever possible.

First round of config related changes to the manpages.

device blah0 -> device blah for PCI devices and busses.

Get rid of deprecated ``net'' argument.

Discourage usage of controller in kernel config files. Reflect this
by changing ``controller'' to ``device'' as per GENERIC and LINT.

$Id$ -> $FreeBSD$

Move lp.4 to man4. It is not i386 dependent.

Fix ppbus and lpt declaration ('0' forgotten). Add info about retrieving
