Mark,
To the extent that it may be helpful here and I can do more if need be, I
built 32 bit R 2.12.0 patched on Snow Leopard (10.6.4), using the R BLAS
rather than Apple's veclib. This is on an early 2009 17 MBP with a 2.93 Ghz
Core 2 Duo (MacBookPro5,2) and 4Gb of RAM.

I only installed the binary lme4 for the R2.12.0. After I remove the lme4, I
change to the R BLAS and reinstall the binary lme4. The results are always
true now.
Hope this information is useful.

This is not just a BLAS issue: I saw it with both vecLib and the
reference BLAS.
The lme4 code is doing exactly the same calculation for M2.

Interesting. No matter what I do here, I can't seem to get the test to fail
using R's BLAS with clean 32 bit builds. So perhaps it is not just the BLAS,
but a combination of R's BLAS and specific hardware?, which gets me into a
realm of knowledge below the event horizon.
Have there been any
I've been trying to get some sort of parallel computing setup running across my
two Macs, one with 8 cores the other with 4. So far, I've mainly been trying
to get MPI to work, but without a lot of success. For example:
Attempt 1:
/usr/local/openmpi/bin/mpirun --prefix /usr/local/openmpi
Rmpi needs help (I'd say a bugfix) if your MPI is not lam (and you
have not told us). See the Rmpi/README file, but the effect is more
serious in 2.12.0 (and the maintainer was informed weeks ago).
I don't understand your notation, but am assuming lines starting with
# are both your comments
