Or activate support for OABI in the kernel...
Of course, this {w,c}ould lead to having two libc: one EABI, and one OABI.
And would require carefully linking the /new/ software against the EABI one.
And many other weird stuff could happen.

Yep, it does! :-)

Hmmm... I don't have any FPU, but I would have thought than an FPU would
speed up float calculations by more than a mere 5x. I will have to make
use of the NEON extensions on my OMAP3530 to check. Low prio, though...
