You should be able to edit the grub line even for the LiveCD. At the beginning of the boot there's a keyboard symbol on the screen, if you press any key you get a boot menu. There is an option there to edit boot params (F6 or so, iirc). All you need to do is add lapic to the boot line.
I am not sure it's a good idea adding lapic for all PC's, this is only usefull for older machines without SMP I think.
