They key point here, as I sort this out, is that *the gcc we currently
have in Fedora* does not support hardfp on vfp-equipped CPUs.

Agreed, this really is boiling down to the question:

(a) Do we use a different compiler than is currently included in Fedora,
or

(b) Do we wait until a version of gcc that supports hardfp on vfp is
available in Fedora (4.5.x, likely in the F15 timeframe).

I don't want to wait for (b) but I think it's a better option than (a).
