Where do you get your firmware from? Is it in the kernel26-firmware
package, or from a third party? Maybe you need to downgrade the
firmware package to make things work.

Also, could you please verify this with an earlier kernel? The commit
[0] aborting on unknown firware is recent, so maybe earlier kernels
give a better error message.
