Console on frame buffer for mpc823

[Jan Damborsky]

Dear Wolfgang,
primarily thank you for your help. But I have not
been lucky to solve my problem. May be I have
old kernel version - 2.4.3.

I have set all this CONFIGS_xxx except for CONFIG_CONSOLE_NOBLANK and
CONFIG_CONSOLE_NOCUR which are not supported in this kernel version.

I have tried *console=tty0* and *console=tty* on command line,
but output is always on *ttyS0* serial console even
during booting message *Console: switching to frame buffer device*
appears.
When trying *cat /etc/group > /dev/tty*, it is send to serial line. Is
it correct ?
How to test that frame buffer is assigned to text console ?

BTW:
[1] CONFIG_SERIAL_CONSOLE is set - it is hardwired
     to CONFIG_8xx - may be it is problem - isn't it ?

                                      Thanks for help , HANYS
