  Not sure what you mean here, but if you upgrade the whole
business to "squeeze", you will solve your problem.

  The issue is that the Debian stock kernel is compiled
with a maximum CPU number of 32 in "lenny", but 512  
in 64-bit "squeeze".

  Alternatively, you can rebuild your own kernel, starting
with the default config file but changing "CONFIG_NR_CPUS" 
to 48 or more.
