I just booted last night's kernel.org tree on a sandpoint 7447A X3B
with serial # > 6000. I used the default config file, just like you.
The switches on the processor card are set as shown below. The "on" and
"off" match the physical markings on the switches as you look at them.
SW1: on,off,off,off,off,off,off,on
SW2: on,off,on,off,off,on,on,on
SW3: on,off,off,off,on,on,on,off
FYI, this is the info printed by dink for you to compare with:

Memory Enabled: [ 128MB at CL=2 ]
Caches Enabled: [ L1I(32K), L1D(32K) ]
Register Inits: [ 32 GPRs, 32 FPRs, 224 SPRs, 32 VPRs ]
