Yes, I know that this thread has contained mixed messages - my post was an attempt to clarify things.
And you pointed me in the right direction. Compiled the bootloader and ipodpatcher. Booted, plays music. I'm sure I'll fiddle.
slightly OT (my apologies.)
If you wondered what I did (I used a new 7.04 ubuntu install):
-make sure you have build-essential installed via synaptic/apt-get/etc
-grab the svn packages for ipodpatcher and rockbox as per compilation guides
-use the arm dev installer script in rockbox tools dir (rockboxdev.sh)
-add the arm bin to path as suggested at the end of the arm toolset installer script
-make the bootloader
-make ipodpatcher, copy the bootloader to where you built/copied the ipodpatcher bin
-ipodpatch away (ipodpatcher -a )
