It should work ;)

What kernel sources did you use for compiling the driver? What was the
exact command line you used to compile it? And what compiler did you

All sounds ok to me. Actually, now that I think of it more, you have
to run wlan-cal after insmoding cx3110x.ko:

chroot /mnt/initfs /usr/bin/wlan-cal

That might help. Sorry, I should document this properly.

You could try to replace cx3110x.ko in /mnt/initfs/lib/modules/, if
there is enough free space. Most probably not.

I haven't ever tried dev rootfs, but I would assume it's not the
problem here.
