ARM926..Alibaba shows a nummber of tablets running on that one.

FPU is optional on all ARM prior to v7.  Popular cores like e Cortex-A8,
Cortex-A9 and Cortex-A5 do not always have any FPU (VFP).  And given how
many mutations of the VFP there are in the ARM world many people throw
up their hands and just install the armsf (ARM soft float) distros.

And we do not want to only support devices less than a few years old?
There are a ton of legacy wrt54g's still out there.
