Wow!  That's pretty impressive, a new kernel build gives me an 
additional _7_ CPUs!

Interesting bits of .config:

CONFIG_M586TSC=y
CONFIG_X86_MSR=y
CONFIG_X86_CPUID=y
CONFIG_NOHIGHMEM=y
# CONFIG_HIGHMEM4G is not set
# CONFIG_HIGHMEM64G is not set
# CONFIG_MATH_EMULATION is not set
CONFIG_MTRR=y
# CONFIG_SMP is not set
# CONFIG_X86_UP_APIC is not set
# CONFIG_X86_UP_IOAPIC is not set

Won't compile with UP APIC turned on, as others have noted.

Aside from /bin/ps getting confused about the system capabilities, it
seems stable.
