We identify devices by their Open Firmware device paths. The encoding of bus numbers is incorrect: idebus_get_fw_dev_path() formats them in decimal, while SeaBIOS uses hexadecimal. With bus number > 9, SeaBIOS will miss the bootindex (lucky case), or apply it to another device (unlucky case). Bug can't bite right now: ich9-ahci has six ports, and the sysbus-ahci created by Calxeda Highbank has just one. Fix it anyway, by changing %d to %x. I couldn't find an Open Firmware spec covering this. For what it's worth, OVMF agrees with SeaBIOS.
