Problems building custom kernel on iSeries

[Wolf Wiegand <wolf@kondancemilch.de>]

Hi,

I'm trying to build a custom kernel for an iSeries within a sid
chroot running on that iSeries. This kernel needs a kernel with an 
attached initrd, and make help tells me, that this can be achieved with
the target 'zImage.initrd.vmode'. However, I don't know how I can pass
this target to make-kpkg. And if I try to just run make with this
target, I get a message that there's no rule for this target. Obviously
I am missing something here. Can anybody give me a hint?

Regards, Wolf
