FreeBSD 6.0-B1 install on HP Pavillion zv5445us hangs after acpi.ko message

[WOB]

Installing 5.4 use to turn off my HP Pavillion, so I thought I would try 
6.0 since I heard it was more laptop friendly.  I have a 6.0-B1 CD that 
I am trying to install from.

6.0-B1 doesn't turn it off, but it does hang with a frozen ACII spinning 
character immediately after displaying:

  /boot/kernel/acpi.ko text=0x41e40 data-0x20e0+0x10b0 
syms[0x4+0x7740+0x4+0x9ead]

If  I interrupt the boot manager, and enter:

 unset acpi_load
 boot

It still hangs with a frozen ASCII spinner character, but there is no 
acpi.ko message.

I don't know a lot about ACPI stuff.
