 Ok.  I think you finally got it this time.  Applied this patch against
 RELENG_6 and it seems to work fine now.  I build and installed the kernel,
 set the loader.conf directives
  hint.acpi.0.disabled to 0
  hint.apic.0.disabled to 0
 and reboot on the system... it works well now, thank you ;)

 Certainly!  The output can be found at:

 Note: the kernel used for this boot was the just-previously-patched one.
