The last digit of the value set in cpu_table ( for example 0x695) is the stepping value reported by cat /dev/cpuinfo. It refers to the release of the processor. It is adviseable to verify that the value corresponding to your cpu is set in cpu_table[]. I have several epia-m boxes some with stepping 1 and some with stepping 8. In this case, I set {X86_VENDOR_CENTAUR, 0x691 } in cpu_table[] to use the box with the cpu wich has stepping 1.
Maybe it would make sense to mask the last digit out for matching against the table then? Otherwise we end up having very vulnerable rom images. Plugging a new CPU in suddenly keeps the system from working and such. Or we need to store an id and a mask. ie. {X86_VENDOR_CENTAUR, 0x690, 0xfff0 } to match 0x69[0-f] with one entry.
