"unable to open initial console" overcame

[Petr Stehlik <pstehlik@sophics.cz>]

Hi,

after long debugging of the suspicious Warning: unable to open an
initial console that turned out to be actually fatal for d-i installer
(because it starts with busybox init </dev/console >/dev/console and so
missing /dev/console kills it) I have just found out that simple 

console=tty0

in bootargs (kernel parameters) fixes it and the d-i boots further on my
AfterBurner040. Easy, isn't it? The question for kernel hackers is why
on AfterBurner this 'console=tty0' is required while on other machines
it's not needed.

The d-i doesn't work yet, it stops somewhere at switching console to
UTF, but for me it's a huge success :-)
