* configure.ac (--disable-default-device-drivers): Transform into...
	(--enable-device-drivers): ... this new option and extend it.
	* i386/configfrag.ac (--enable-lpr): Adapt to that.
	* linux/configfrag.ac (AC_OPTION_Linux_ix86_at, AC_Linux_DRIVER):
	Likewise.
	(AC_Linux_DRIVER_qemu): New definition.  Use it for the `floppy', `ide'
	and `ne' device drivers.
	* doc/mach.texi: Document all that.

 @subsection Turning device drivers on or off
@@ -564,14 +563,16 @@ Each device driver has an associated configure switch.  The following table
 indicates whether a device driver is enabled by default or not.  It also gives
 --- if possible at all --- the configure switches to use for disabling or
 enabling device drivers, in case you're not satisfied with the default choices.
-Where a @samp{--disable-*} switch is given in the table, the device driver is
-enabled by default and you have to use the switch to disable it and vice versa
-for the @samp{--enable-*} switches, the device driver is disabled by default
-and you have to us the switch to enable it.  To have all device drivers
-disabled that can be disabled and would otherwise have been enabled by default
-you can specify the @samp{--disable-default-device-drivers} switch and then use
-individual @samp{--enable-*} switches to enable only those you actually want to
-have enabled.
+You can specify @samp{--enable-device-drivers=WHICH} (where WHICH on
+@samp{ix86-at} must be one of @samp{default}, @samp{qemu}, @samp{none}) to
+preset a certain subset of all available device drivers.
+@samp{--enable-device-drivers} is sugar for
+@samp{--enable-device-drivers=default} (and is the implicit default
+nevertheless) and @samp{--disable-device-drivers} is short for
+@samp{--enable-device-drivers=none}.  @samp{qemu} will include only the set of
+device drivers that is useful when using the resulting kernel binary to drive a
+Hurd system in the @acronym{QEMU} system emulator.  This is only useful for
