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.
Note: this box currently run the RELENG_6 branch, build at Wed Nov 30
