Ah, yes, that's part of the lowmem testing.

The doc probably just ended up wrong by just not getting updated,
because we don't have people who both care about updating them, and have
access to the hardware or know the qemu tricks to test all archs.
I see that in the lowmem package,
bbb4ed4c4da20d585cf30ceba9f0987173d3ac70 raised the default levels from
32MB/64MB to 120MB/155MB, that being the minimum numbers that were
actually seen to work on at least some arch.

Probably not, as seen in the values in the lowmem package.
