OK, after setting the kernel line with "noapic" and removing "splash", it boots with all cores. I haven't done more than this boot, although... the real first boot gave me some dreaded "not responding" messages, then it hung on initializing APIC.
I don't understand why the splash screen makes a difference here, but again I'm not a developer nor a PC architecture geek.
