>Environment:
System: NetBSD/zaurus 5.99.47 on SL-C1000,
but 5.1 also affected
Architecture: arm
Machine: zaurus
>Description:
NetBSD's zbsdmod.o lkm driver on Zaurus Linux can't load GENERIC kernel.

>How-To-Repeat:

Bootstrap on Zaurus Linux:

$ su
# insmod zbsdmod.o
# exit
$ cp netbsd /proc/zboot

 [hang with corrupt screen]

>Fix:
As OpenBSD's zbsdmod, shrinking memory size to 5MB works around,
though we can't load larger INSTALL kernel in that case.
http://www.openbsd.org/cgi-bin/cvsweb/src/sys/arch/zaurus/stand/zbsdmod/zbsdmod.c.diff?r1=1.5;r2=1.6

OpenBSD's zbsdmod.o can also load NetBSD/zaurus GENERIC.

We also need actual install document...
