*sigh* ok, I'll prepare something.

54? with a five in front of the four?
Either you or your harddisk partitioning tool wrote nonsense into the rigid
disk lock structure.

Suggestion: I've heard the rumour that Linux doesn't really look at the
partition type, is this true? In this case you might want to change it to
the 'NBS\1' which NetBSD uses as a swap partition, to share it.

"However obscure"? Yes. Write the adosfs writing code.

I don't understand the connection.

If you binpatch on the AmigaOS side (The Adosfs binary of the binpatch
program should be on the Regensburg NetBSD/Amiga ftp archive) you dont
have the problem.

If you want to do something else than what I understood, you can use 
"bffs" to read the kernel off the NetBSD root partition.
