Comment(by leif):
So, I did test this with Sage 4.7.2.alpha2 on my "last" 32-bit machine, a
Pentium4 Prescott (which has SSE3) running Ubuntu 9.04; my other Pentium4
(Northwood, without SSE3 / PNI) recently died, and I won't revive it in
the near future.
The good news are: The patches all still apply to 4.7.2.alpha2, though
many hunks with partially large offsets, but no fuzz.
The bad news: I expected some numerical noise because of 32-bit
architecture with (there rather rare) SSE3 (`-mfpmath=sse`), but also
experienced at least one segfault (in `sage/rings/homset.py`). I'll have
to investigate the rest, for now just:

(The tail of the log. More to come later.)
Note that I didn't test in parallel, although with some other CPU-greedy
process running, but time-outs are unlikely. Vanilla 4.7.2.alpha2 passed
all tests in exactly the same setting (and I did rebuild all dependent
packages when installing the Python 2.7 spkg, modulo missing extension
module dependencies in `module_list.py`).
