I think it's a consequence of not choosing CONFIG_FIRMWARE_IN_KERNEL=y.

That caught me out on PowerMac G5 trying mmotm yesterday, it just hung
for a few minutes in earlyish boot with a message about tg3_tso.bin,
and then proceeded to boot up but without the network.  I was unclear
whether I'd been stupid, or the FIRMWARE_IN_KERNEL Kconfigery was poor.

I avoid initrd, and have tigon3 built in, if that's of any relevance.

I wonder if that's Andrew's problem with 2.6.26-rc8-mm1 on his G5:
mine here boots up fine (now I know to CONFIG_FIRMWARE_IN_KERNEL=y).
