You didn't say anything relevant to your case: which version of FreeBSD
are you using?, which architecture?
ACPI is pre-loaded as a kernel module in all recent versions of FreeBSD
and adding it directly in the kernel wouldn't accomplish anything. I
assume you're using i386 (e.g. the 32-bit variant of FreeBSD). In this
case you have only two options if you want to use 4 GB or more memory:
* Use a PAE kernel, which works fairly well, but doesn't support kernel
modules (if you are not familiar with kernel modules then you probably
don't need them so ignore this). There's a pre-packaged kernel
configuration named "PAE" for this.
* Switch to a 64-bit version (usually, this means you have to reinstall
the system using the 64-bit install CD). The 64-bit version is called
"AMD64" and it also runs on Intel CPUs.
