This indicates you didn't copy acpi.ko to / and maybe copied acpi.kld.
Thus there is no debugging output. If it was acpi.ko, it would be labeled
"elf module" as below:

Since the kld was not the kernel module, your kernel went and loaded the
original acpi.ko from /boot/kernel, which doesn't have debugging enabled.
Please check against the instructions I list again below:
