Revised CPUID/cache info - for review

[Sean Kelly]

No time to tidy, but I can confirm that it works:

Vendor string:    GenuineIntel
Processor string: Intel(R) Core(TM)2 CPU         T7600  @ 2.33GHz
Signature:        Family = 6 Model = F Stepping = 6
Features:         MMX SSE SSE2 SSE3 FXSR
Multithreading:   1 cores / 1 threads
Data caches per CPU:
L1 ways = 8 linesize = 64 size = 32K
L2 ways = 16 linesize = 64 size = 4096K
