Missing ttys on SC520

I have two AMD Elan SC520 boards which are basically identical; the only visuable difference is that one bootloader switches on the PCI-VGA card and displays a splash screen before starting the Linux kernel.

The board without splash screen boots 2.4.21 just fine, especially there are entries in /dev/vc/* for the virtual terminals. The splash screen board does also boot, but there is only /dev/vc/0 available. Both boards run the same kernel image and the same user space.

Any idea how this could be caused? I'm not that firm with the terminal code to find out which part fails while probing what...
