oops, guess I missread the conversation I was reading, thanks for clearing 
that up.

So If I'm reading that correctly, there is 0x00bfc000 bytes availabel at an 
offest of 0x00004000, since grub is asking for 0x001fb000, and that is less 
than 0x00bfc000... I don't get why it's failing.

(And just for reference: no changes to the setup in nvram and my crusty old 
yaboot loads just fine, boots the kernel and I'm off and running... the 
machine has been beaten on pretty hard on a regular basis, so hardware wise 
things seem to be in good shape.)
