Ok, thanks for your answers!
I have been working with PowerPC processors in the past and looking at Freescale's 8641D it is possible to boot two different kernels on it's both cores.

Is there a way to boot a normal standard home x86 dual core PC with two

The idea is of course to give the Kernels their own address space and
their own rootfile systems, the devices would be unique for each kernel
etc.

Can this be done with a standard BIOS and GRUB/LILO?

No. There are way too many shared resources, such as address space and
interrupt system. You need a central resource to arbitrate those
resources, i.e. a hypervisor.
