I am using the standard OpenEmbedded ARM EABI toolchain and I am not
seeing this issue on the NEO1973 phone (Samsung ARM SOC), or a Xscale
platform.  Both kernel configs include:

CONFIG_AEABI=y
CONFIG_OABI_COMPAT=y

As I understand it, floating point is emulated at the library level,
and not in the kernel with this setup.

Are you building the mono-1.2.5pre5 package?  I never did find a
solution to the ARM floating point issues with 1.2.4.

Yes, I have mono running on a Xscale platform.

Excellent!   Thomas Kunze created the original mono recipes.
