On rp34xx machines Linux detects the AUX port of the DIVA GSP card (PCI subsystem id 0x1291) before the console port of DIVA GSP and as such the AUX port becomes ttyS0 and the console port becomes ttyS1. Since the palo bootloader by default sets the console output to ttyS0 if no keyboard & monitor is attached, all Linux kernel boot messages get lost. Avoid this problem by ignoring the AUX port. There is no external serial port connector for AUX, so we won't miss this serial port either.
