Look at the path in the patch start.  If it's "sys/dev", then patch from 
your src dir.  If it's "src/sys/dev", patch from above the src dir.  If 
it's just "file.c", then you have to find file.c and patch from there 
(but few people generate diffs this way, it's bad form).

For acpi, then just:
cd /sys/modules/acpi/acpi && make && cp acpi.ko /

Then at the loader prompt:
load /acpi.ko

You don't want to use "make install", otherwise you overwrite your known 
good acpi.ko
