+          <p>
+          Certain models of HP laptops have an ACPI BIOS that is incompatible with the
+          Linux 2.6.18 kernel shipped in &releasename;, which would prevent the fans from
+          spinning up leading to unnecessary heat stress.  The kernel therefore disables
+          ACPI support internally when it detects certain ACPI BIOS versions.  Models
+          known to be affected by this change include the HP nx6125, nx6325, and nc6120
+          models.
+          </p>
+          <p>
+          Users who require ACPI support on these systems may install a Linux 2.6.19 or
+          later kernel.  Please see bug
+          <url id="http://bugs.debian.org/404143"; name="#404143">
+          for additional information.
