binary acpi tables

I get multiple acpi errors on boot preventing acpi_asus_wmi module to load
successfully. See: dmesg-freebsd.txt

I checked also Linux (6.19) and there acpi initializes correctly and asus
modules are loaded succesfully. Keyboard backlight, volume and display
brightness working fine.

Tried multiple workarounds including modification or DSDT but to no avail.
Below from dmesg is interesting:

"Firmware Warning (ACPI): Possibly buggy BIOS with ACPI_TYPE_INTEGER for
function enumeration"


Attached: 

1. ACPI tables in binary format.
2. FreeBSD dmesg. 
3. Linux dmesg.
