Re: [linux-fbdev] Console on frame-buffer... how?

I dont pass anything to the kernel... in the PPC distribution, a kernel
parameter is CONFIG_SERIAL_CONSOLE that initializes a console using the
serial driver. No parameters are required. It only add a call in
'console_init()'.

I looked at the sources, but i still think there's something wrong on
console initialization (this is 'main.c'):

CONSOLE_INIT
    CON_INIT (vt initialization)
    CONSOLE_8xx_INIT (serial console on the PPC)
TTY_INIT
    RS_8xx_INIT (serial driver on the PPC)
VIDEO_SETUP

Then, i see that VT is not registered because at CON_INIT, the functions
tests the value of 'conswitchp' before running any 'con_startup' function,
and it is NULL. Who should initialize it if this function has to be called
before any other one that initializes the framebuffer? I cannot change
virtual terminal because VT is not registered, then there is something wrong
on this, isnt it?

Sorry, but it still doesnt work!
