Default [B]Problems with installing Debian on G1[/B]

Hi i am trying to install Debian on G1 according to instructions of saurik http://www.saurik.com/id/10 but couldnt proceed from initial steps. I have cupcake 1.5 by JF installed.

1.) couldn't insmod ext2.ko says failed, "exec format error"

2.) Tried to skip that step and next one mkdir $bin #-p (gave error tht location is not writable) i have root privileges , but couldn't write to /data/local dir.

what should i do, where does the problem lie?

please do answer if anybody have an idea , thank you in advance.
