Sigh.

Yup. That's correct

@Sam: I just checked, that your machine has a serial port. That's a
good start :)

Do you have a second computer around with a serial port ? If yes, then
please add the following to the kernel command line:

       earlyprintk=serial,ttyS0,115200 apic=debug

and connect the serial ports with a null modem cable. Fire up a
terminal program on the second machine and capture the output.

Thanks,

	tglx
