Ah!  OK, thanks for the explanation...

For my konqueror/javascript problem, the konqueror developers seem to
think it's outdated dtoa code...  But I'm not ruling out other
possibilities, as this is the first time I've done any floating point
on this box.....

arm-linux-gcc (GCC) 3.4.4

*multilib_defaults:
marm mlittle-endian mhard-float mapcs-32 mno-thumb-interwork

Does this look about right for the TS7xx0 boards?

This is the relevant chunk of the kernel .config:

CONFIG_ARCH_EP9301=y
CONFIG_CPU_32=y
CONFIG_CPU_ARM920T=y
CONFIG_CPU_32v4=y
CONFIG_DISCONTIGMEM=y
CONFIG_HOTPLUG=y
CONFIG_NET=y
CONFIG_SYSVIPC=y
CONFIG_SYSCTL=y
CONFIG_FPE_NWFPE=y

Would soft-float be better (i.e. faster, smaller code, or something?)
 Performance is an issue for me in the user interface, and if I can
speed it up 'for free' that would be good.

And it would not be a big deal to recompile everything for it....
