Revisiting the 486sx issue
curaga:
If the FPU emulation works, there should be no need to recompile any libs.

That was my thinking as well, the kernel will trap any attempt to use the FPU and handle it. So far it appears to have done so, including anything that might be in the application I need to run.
Most of my problems so far are down to the fact that I'm compiling on my home machine via ssh, then copying it to the laptop at work and creating the bootable image on that to run on the target. If I get distracted and forget a step (such as forgetting to copy the bzImage or the module set or save the .config before trashing it) then it doesn't work. Now I'm at home and have a more seamless environment with fewer distractions.
Performance-wise, it'll do what I need it to do, and that extra $20 (I make it $30, looking at the WDL site compared to the Norhtec one) is worth saving if we sell enough systems.
ETA: with a clear brain it worked first go. Some optimisation now needed to reduce the module count because it does take ages to boot and unpack initrd.

Are you in the US? The NorhTec site said shipping was $55, which makes the total cost $88 + $55 = $143. WDL doesn't list shipping charges on their site, but they sell the eBox-2300SX for $100 (less for 25+ units). If it costs less than $43 to ship then you can save even more.
llondel:
I'm in the UK, so shipping to here is different (but comparable). For one or two units it's not cheap, but buying a hundred will bring the shipping cost per unit right down.
I did mention the eBox-2300sx to those who will have to do the procurement, it always helps to have options.
For reference for anyone compiling the kernel, it wouldn't work until I told it to stick to 4GB and took out a bunch of VM-related options from the processor page of menuconfig. I can post another diff (-u) if interested.

Yes, please, or you can attach your .config to a post. I'd recommend editing your earlier post to remove the previous diff to avoid confusion.
