Ok, this is somehow all moving...

I am about to write a howto on getting netbsd onto the Jornada but one 
of the biggest barriers is getting the netbsd kernel to compile, so I am 
  trying to write as much info as possible about compiling the kernel on 
NetBSD. The compile errors are mostly ASM errors and I had to set some 
constants in order to get it to nearly compile, there were errors 
regarding bios32 on my i386 platform.
So my current problem is:

bash-2.05a# /usr/src/tools/obj/tools.NetBSD-1.6D-i386/bin/nbmake-hpcarm
making sure the compat library is up to date...
`libcompat.a' is up to date.
making sure the kern library is up to date...

and Yes I updated my nasm and all, perhaps I am a bit to bleeding edge?

Anyway getting on writing my findings up...

is there any native apm support? any standard apm stuff?

well not that I am aware off, I had these problems too, perhaps we need 
to debug some registers to see what state their at before and after...
