"D'Oh!" -- H. Simpson.
"Nevermind" - Emily Litella.

Actually, FIRMWARE_IN_KERNEL *did* make a difference - it busticated the tg3
driver and while fighting with the 'firmware: requesting tigon/tg3_tso.bin'
errors I had just inflicted on myself, I found the 'requesting intel-ucode/060f06'
messages as well - and totally failed to notice that the *previous* kernel
and initscripts had *all along* been doing a modprobe, which generated 2 requests
(one per CPU) which failed, and then the initscript ran microcode_ctl *anyhow*,
papering over the two failed requests.. ;)
