boot eax = 0x2badb002
boot ebx = 0xf0000
boot arg = 0x2

That doesn't look good. 0x2badb002 instead of 0x100060 in the working
log.  I don't know much about OpenBIOS, but I'm happy to help if it
looks like the resource allocation is breaking it.  Have you tried it
without the printk buffer enabled?
