Hmm, maybe but you have code in cpu_detect_cache_sizes that's X86_64 only..

void cpu_detect_cache_sizes(struct cpuinfo_x86 *c)
{
         unsigned int n, dummy, ebx, ecx, edx, l2size;

         n = c->extended_cpuid_level;

         if (n >= 0x80000005) {
                 cpuid(0x80000005, &dummy, &ebx, &ecx, &edx);
                 c->x86_cache_size = (ecx>>24) + (edx>>24);
#ifdef CONFIG_X86_64
                 /* On K8 L1 TLB is inclusive, so don't count it */
                 c->x86_tlbsize = 0;
#endif
