Why do you even enable APIC on an old laptop? We tried it a few times,
it's just not possible. I'd say, about one in ten to one in five of 2002
vintage laptops will not even boot, let alone work when APIC is enabled.
Some of them are well known, like Dell Lattitude 610. I expect this to
change with dual-core laptops, but for now the rule is: UP kernel,
No APIC, for distro kernels at least.
