+  <ul class="incremental">

   <h1>Out-of-tree modules</h1>
+  <p>
+    The kernel team does not encourage the use of out-of-tree modules.
+    However, we support them by providing development packages and by
+    avoiding ABI changes during a stable release.
+  </p>
+  <p class="incremental">
+    Debian has two packages to aid in building out-of-tree modules:
+  </p>
+  <ul class="incremental">
+    <li>
+      <tt>dkms</tt> - builds and installs modules automatically.  Can
+      build packages for installation on other systems.  Also
+      supported by Ubuntu and SUSE.
+    </li>
+    <li>
+      <tt>module-assistant</tt> - builds packages as directed.
+      Uses a separate package name for each kernel ABI.
+    </li>
+  </ul>

   <h1>Firmware files</h1>
+  <ul class="incremental">
+    <li>
+      Most peripherals have microcontroller running non-free
+      firmware; some require host to load it
+    </li>
+    <li>
+      Several drivers used to include firmware, making kernel
+      non-free.  Fudged with GRs for a while; finally fixed in squeeze
+    </li>
+    <li>
+      Users with these devices - almost any wifi card, some network
+      controllers and Radeon GPUs - will still need the firmware
+      files installed
+    </li>
+    <li>
+      Kernel team maintains <tt>firmware-nonfree</tt> source package
+      covering most firmware files that are clearly redistributable
+    </li>
+    <li>
+      Also collected in linux-firmware.git repository maintained by
