- Please make sure that your BIOS is up-to-date.
- Dump your DSDT into ASL and grep it
  #acpidump -d > your.asl
  #fgrep -i '"Windows' your.asl

  If this displayed something like this:
      "Windows 2001"
  then try
      set hw.acpi.osname="Windows 2001"
  from the boot loader and see the difference. This won't fix anything
  and you may be seeing other problems, YMMV.

- Does the following command sequence produce the same error messages?

  #iasl -c your.asl

  If so, you may want to fix your ASL, compile it into AML, put it somewhere
  in the root filesystem, and tell boot loader to use it.

  # vi your.asl
  # iasl your.asl
  # mv acpi_dsdt.aml /boot/
  # echo 'acpi_dsdt_load="YES"' >> /boot/loader.conf

For more hints and detailed instructions please refer to the
Config and Tuning handbook page posted on submit@ for reviewing.
