Just to add here: from my local tests with other older images, the text is there on the black screen but just extremely faint. My guess is that it's an endian-related bug in OpenBIOS programming the VGA registers but haven't had much time to dig into it.

The booting process stops with CPU at 100%. I can choose to boot "install-2.4" or "install" which both hangs with the last output being "Loading ramdisk". I have also tried using the git-tree which crashes qemu with the message "qemu/memory.c:1183: memory_region_add_subregion_common: Assertion `!subregion->parent' failed." before even showing anything. Additionally, qemu 0.14.1 shows the same behaviour but qemu 0.13 and 0.12.5 can boot beyond the "Loading ramdisk" message but stops immediatly afterwards with a messed up console window (letters are pushed into another, which makes them barely readable) when using "install". Also "install-2.4" boots with 0.13 and 0.12.5 beyond the "Loading ramdisk" message but stops with the last message being now "returning 0x01400000 from prom_init".
