how about reading my bugreport that you replied to:
http://lkml.org/lkml/2008/4/11/34
It gives an answer to your question, trivially so. It includes an easy link to the very config that failed:
http://redhat.com/~mingo/misc/config-Thu_Apr_10_10_41_16_CEST_2008.bad
which would tell you:
CONFIG_NR_CPUS=8
so no, it's not 255 CPUs exhausing RAM ...
