Installing a custom kernel on Debian S/390(wheezy/sid)

Guy, I've just finished installing the S/390 version of wheezy/sid into a Hercules emulator (the one from the Xubuntu repositories, seems to work fine).

Everything is working including networking, but to my dismay I noticed there's no DECNET support compiled into the kernel (yes, I am that nuts, I want DECNET on an S/390).

Anyway, so I downloaded kernel sources for linux- ( seemed the closest to 2.6.32-45, which was shipped with the distro) from kernel.org and did a make menuconfig. All went swimmingly.

I am now running the proper "make" to build the kernel, and it seems to be working fine, too.

Now to my question: How do I _install_ this kernel, ideally as a new boot option when I IPL the box.

I assume I have to:

1. Generate a new initramdisk
2. Put the kernel somewhere
3. Put the new modules somewhere
4. Modify the bootloader

Now it's been a LONG time since I've done this (think slackware with lilo and kernel 1.x) so I have no idea how to proceed, especially on an S/390.

Anyone got any pointers?

As for my current setup, here's some data:

#cat /etc/debian_version:

#cat uname -a:
Linux version 2.6.32-5-s390x (Debian 2.6.32-45) (dannf@debian.org) (gcc version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Sun May 6 03:12:45 UTC 2012

# cat /proc/version
Linux version 3.2.0-23-generic (buildd@crested) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu4) ) #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012

PS: In the future, could you guys maybe include DECNET support in the mainstream kernel releases? Or is this a problem?
