Yes, before cpu_detect, the family is set to 4. And with "family" I mean
#define X86 new_cpu_data+CPUINFO_x86
and not the hardware family of the CPU and what you mean is that when
we boot 32-bit on a hardware family != 4, we run with X86 == 4 until
cpu_detect runs.
So basically we're saying the same thing. :)

Yes, this part of the commit message.
