Am, --with-firmware-path="/lib/firmware/updates:/lib/firmware" configure
switch should enable udev firmware loader iirc. But your log says:
"systemd-udevd[1579]: IMPORT{builtin}: 'firmware' unknown", which
confuses me. From what I know, for newer kernel versions, systemd/udevd
won't use its firmware loader, but the kernel one. It should be enabled
in Device Drivers -> General Configuration (the first entry in Device
Drivers), not sure what's the name, or you can build firmware into
kernel in the same menu (CONFIG_EXTRA_FIRMWARE). See BLFS instructions
for Xorg ATI Driver for an example on how to do that.
