Hi Daniel!

And what happened? Are you sure you recompiled and booted the new kernel with 
CONFIG_FIRMWARE_IN_KERNEL=y?

Obviously bnx2.ko is loaded from initramfs. At that time the root filesystem is 
not accessible. I expected CONFIG_FIRMWARE_IN_KERNEL=y is sufficient to solve 
the problem.

Here is what I would try:
- make sure the firmware is included in your kernel, or
- keep bnx2.ko from including in initramfs (unless you boot via network), or
- include /lib/firmware/bnx2/bnx2-mips-06-4.6.16.fw in initramfs

HTH
