And indeed the one of the tables was screwed. There is a sneaky typo
in calculating how far to advance the pointer in the CPU table - its
doing  strlen(buf) instead of strlen(cpu_manufactuerer) which on my
particular system offset things by 6 bytes. Attaching the trivial
patch to fix it - applies on top of your patch in 11686.
