You just need this on 32bit machines with more than 4GB of RAM.
No, you also need it on machines with 4 GiB of RAM and remapping
capability, in order to use the part of the RAM which is remapped beyond
the 4-GiB boundary due to the "PCI hole". Usually the remapped memory
amount is about 500 MB, but I have seen machines remapping 1 GiB or even
2 GiB, leaving only 2 or 3 GiB of usable RAM with a non PAE kernel.
Note that the non PAE kernel in older Debian versions up to Jessie
lacked multi-processor (including multi-core and hyper-threading) support.
