Just a few things I noticed while hacking away at Haiku on PowerPC:
The following OpenFirmware commands aren't implemented:
erase-screen toggle-cursor
It does seem like these are implemented after looking at the sources. However we receive the following error when they are used:
undefined defer word toggle-cursor undefined defer word erase-screen
I didn't get those when I last tried, it just hung. Where do you see these errors? Please share details on what versions and command line you use. Thanks!
If you skip doing the new page table...

You can get all the way to the graphical splash screen for Haiku :)
You will have to press return 3 times in the boot loader menu to load the kernel.
