 Yes, sorry: the layout of the website was changed recently.  Here are
 the corresponding files (using RELENG_5 at this time):

 More precisely, here is a little tab... to be more accurate (i hope):
 
 ---------------------------------------
  USB support   |   ACPI   |   APIC    |
                ------------------------
                | on | off | on | off  |
 ---------------------------------------
 KO!            | XX |     | XX |      |
 ---------------------------------------
 ok             | XX |     |    |  XX  |
 ---------------------------------------
 ok             |    |  XX | XX |      |
 ---------------------------------------
 Did not boot(*)|    |  XX |    |  XX  |
 ---------------------------------------
 (*) The boot disk seems not be able to be used for the root mount, i.e.
 ufs:/dev/ad0s1a in my case.
