Did you enable ACPI? Ah... did NOT have ACPI enabled. Did not know it had to be, for SMP to work! I enabled it, compiled the kernel, and /proc/cpuinfo sees 2 CPUs, but top doesn't. After spending ages trying to figure it out, I found the version of top that comes with Debian 3.0 does NOT have SMP support. So I downloaded the backported version from: http://people.debian.org/~nobse/debian/woody/backported/procps/ and after top launches, press 1 (or set the appropriate cmd line parameter) and it works great. I did ACPI a little different than you though... I have: > # CONFIG_ACPI_HT_ONLY is not set set as y/1 (and therefore everything else set as n/0), as I don't need all the "acpi_power" and other stuff, just want SMP to work. So it's working now.
