-	  The DSDT (Differentiated System Description Table) often needs to be
-	  overridden because of broken BIOS implementations. If this feature is
-	  activated you will be able to provide a customized DSDT by adding it
-	  to your initramfs. If your mkinitrd tool does not support this feature
-	  a script is provided in the documentation. For more details see
-	  <file:Documentation/dsdt-initrd.txt> or <http://gaugusch.at/kernel.shtml>.
-	  If there is no table found, it will fall-back to the custom DSDT
-	  in-kernel (if activated) or to the DSDT from the BIOS.
