Dell Latitude E6400, F10-uptodate as of yesterday, 2.6.29-git14 plus
Vegard Nossum's fix to acpi/battery.c to allow booting (this specific
WARNING was also printed during -git13 boot, which would eventually
hang prior to Vegard's patch).
dmesg excerpt:

Microcode Update Driver: v2.00 removed.
System seems to work at the moment (apart from unrelated X/VT
issues I plan to report in a detailed fashion by the end of this week).

I encounter this warning too.
Seems commit af5c820a3169e81af869c113e18ec7588836cd50 intends to hunt
this warning when microcode_init_cpu() failed.
