Your P4-based Latitude probably has a different BIOS than the buggy P3-based ones, and it may work better. Try commenting out the local_apic_kills_bios entry for "Dell Latitude" at around line 692 in arch/i386/kernel/dmi_scan.c and rebuild the kernel. If it
(ahem) I had tried that in 2.5.58 already ;)
However I rebuilt 2.5.59 with that change, and I'm not going further:
No local APIC present or hardware disabled

Ah, your P4 needs another patch. Edit arch/i386/kernel/apic.c, function detect_init_APIC(), at line 631, and remove the "&& cpu_has_apic" after the "boot_cpu_data.x86 == 15" test. (Or check if your BIOS can be set up to boot with the local APIC enabled.)
