Is there an another way to find out if start_kernel() has been called?

Commandline? How can i see which commandline is passed to the kernel and
how can i change it?

Okay i've changed to apex. Still the same problem. I've loaded the
compressed kernel via "xreceive 0xc0008000"

I've appended the complete output of an apex session with a compressed
kernel_image. I switch on the debug output in
"arch/arm/boot/compressed/head.S" to see the memory dump.

The commandline is the default:
console=ttyAM1 root=/dev/hda1 mtdparts=lpd7a40x_norflash:2m(boot),-root
