The version did change. One '0' less.

Users don't read even if you put in there:

	"Corrected error, no action required."

User still complains about maybe her hardware going bad and "should I replace my
CPU" yadda yadda...

But whatever, since both of you think this is sooo important, then pls do this:

Success: "Reload completed, microcode revision: 0x%x -> 0x%x\n"

Failure: "Reload failed, current microcode revision: 0x%x\n"

Or something along those lines.
