NSLU-2 NAS - how ??

[amacater@galactic.demon.co.uk (Andrew M.A. Cater)]

Like an idiot, I had a working Debian kernel on my Slug which I then
over-wrote.  

I can re-flash with the Linksys flash, which works fine.

I can re-flash with the Openslug-2.7beta binary, which works fine.

Attempts to use the Masterfile from www.nslu2-linux.org fail -
linux-ipx4xx-csr fails currently.

Neither debianslug (little endian) , nor openslug will build from scratch. 
Neither will Debianopenslug - which is big endian.

I've had a couple of tips from Martin Michlmayr - but I'm now _entirely_
stuck.

All clues welcome :)
