I built the cp210x module using the NAO kernel tree:

I placed this into the drivers/usb/serial directory in the NAO system, but it didn't work (no surprise there!). It gave me an error:
"Invalid module format" when I tried modprobe or insmod.
Just a quick test, what happen if you do: insmod -f /path/to/the/module.ko ? IMHO, quite likely the message you saw happened since you compile the kernel module with different version of gcc and/or different gcc parameter, that somehow yield binary incompatibility. Another thought, what arch do you use when you compile that kernel module? AMD Geode too? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
