SMP on AS4100 not working ?

[alpha-linux at gmx.net]

i got some bad feelings about smp on as4100.

during boot i get this kernel messages:

when i do a top, i only see 1 cpu:

L3 cache                : 4096K, 1-way, 64b line

in cpuinfo there a 4 cpu detected and active.

so how can i test this to be really sure, if it's running on all cpu's ?
smp-kernel is running:
Linux dhcp-17 2.6.11-1.1180axp_FC3smp #1 SMP Mon Apr 18 14:35:11

btw: the dnetc client for alpha is failing with a segmentation fault.
