I just noticed that my blog entry only shows the memory info.  Here  
is some sample CPU output from an older box I have kicking around:

*-cpu
           description: CPU
           product: AMD Athlon(tm) XP 2100+
           vendor: Advanced Micro Devices [AMD]

           bus info: cpu at 0
           version: 6.6.2
           slot: Socket A

           capacity: 2500MHz
           width: 32 bits
           clock: 133MHz

              capacity: 128KB
              capabilities: synchronous internal write-back
         *-cache:1
              description: L2 cache

              capacity: 256KB
              capabilities: synchronous external write-back


Compared with the output of cat /proc/cpuinfo on the same box:

processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 6
model           : 6
model name      : AMD Athlon(tm) XP 2100+
stepping        : 2
cpu MHz         : 1735.648
cache size      : 256 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
