StabilityTest has a natively compiled version of Linpak (the normal Linpak for Android is dalvik-based and thus even more terrible). It would be interesting to compare the results a bit.

Interesting. Was not aware of that test. The MFlop numbers are still not reflecting what should be possible with the processors. LINPACK is a somewhat misleading benchmark name. Linpack tests are actually not a single benchmark. Rather, it is more of a "Calculate this using whatever algorithm you feel appropriate, as long as results are accurate and stable". Most Linpacks on servers are rewritten to heavily use the BLAS, and heavily depend on good matrix multiplication performance to the point where Linpack performance is close to the flops in a matrix multiplication benchmark (such as mine).
However, reference Linpack implementations in C/C++ also exist. These are more for reference/learning and do not use the BLAS and not used to test performance on servers. Given the relatively low FLOP rating you got, I think perhaps what they have compiled is this reference version.
edit: However, it should still be a good benchmark and hopefully not as terrible as the Java version.
