That's probably because you didn't specify -p to patch program:

$ zcat acpi-update.patch.gz | patch -d /sys -p0

Sorry that I didn't mention this in the previous mail.

The only reason that I created dev/acpi was so as I could
immitate /sys/modules/acpi tree in FreeBSD-CURRENT. Originally
I was planning to populate acpi submodule directories under
/sys/dev/acpica5 and use bsd.subdir.mk, but then, because of my
lack of knowledge, nothing in acpica5 was compiled. IMHO calling it
acpi is more intuitive than as acpica, but I'll try to rewrite the
patch as you suggested. I also considered moving freebsd acpi code
under /sys/contrib and keeping our local changes as patches, but
maybe it's a bit too far.

Too bad Nate has imported newer ACPI-CA code a few days after I posted
the patch...
