Sergei,
I'm using kernel 2.6.24 now (before I used 2.6.21-rc4). I do see the
console messages on the framebuffer device.

Kernel options:
console=ttyS0 root=/dev/mtdblock0 rootfstype=jffs2 rw
video=au1100fb:panel:KERN_AU1100 tsdev.xres=320 tsdev.yres=234
console=tty0

If I omit console=tty0, then there is no output on the framebuffer
device or the serial port. I also tried setting the I/O address and so
on, but no luck.

Hello.

Hello all,
I didn't follow the entire discussion, but I might have similar 
problems on the AU1100 SoC. The AU1100 also has 16550 style serial 
ports. The serial console doesn't work even though I specify 
console=/dev/ttyS0 on the kernel command line. Once a getty is 
started, the serial port is active and working fine.

    This is not at all related to the discussed issue, so 
I've changed the subject. The console works like charm 
(seemingly for everybody, which kernel version are you using?
