Bug#679545: IA64 (Itanium) Wheezy, doesn't detect DVD drive and NIC, patch proposal

First problem, the build-in IDE/PATA host adapter of the chipset isn't  
detected
===============================================================================

The host adapter has the PCI-ID Intel, 24cb.
The associated definition is
#define PCI_DEVICE_ID_INTEL_82801DB_11	0x24cb
in include/linux/pci_ids.h in the kernel sources.
The designator PCI_DEVICE_ID_INTEL_82801DB_11 is only used in
drivers/ide/piix.c, line 434.

This driver is disabled in the current kernel config.
In the past the PIIX IDE driver was enabled as a module in the Debian Kernel.

Rev. 16427, Feb 25, 2010
These committed patches move some PCI-IDs from drivers/ide/piix.c to  
drivers/ata/ata_piix.c, and changed the kernel config in order to  
exclude ide/piix for *all* architectures.
PCI_DEVICE_ID_INTEL_82801DB_11 is one of the IDs which remained in ide/piix.c.
I don't know the reason for that; I realized that the mentioned  
patches are no longer in the Kernel 3.2.0-3 of Debian but ide/piix is  
still excluded from the Kernel.
Please could we include the ide/piix again as a module - just for the  
IA64 architecture?
A patch proposal is below.

I'm still using Lenny which has a 'debootstrapped' Wheezy userland on  
a chroot.
I built the kernel-image-3.2.0-3-itanium-di package again; copied the  
generated udebs into the build/localudebs directory of the  
debian-installer and build the debian-installer package after that. I  
extracted the generated debian-installer-images_20120712-ia64.tar.gz  
to a local mirror which already had files from the Wheezy beta-1. I  
built a set of netinst CDs with the debian-cd packge which used the  
mentioned local mirror.
The installer could detect the CD drive when I tried the created  
netinst CD. It took some packages from the CD and pulled some others  
from the net - in my opinion it works as it should.


Second problem, the Intel E1000 NIC isn't detected
==================================================

Ok. I realized that nic modules aren't needed in the initrd for the  
debian installer. The installer gets the nic modules from somewhere  
else in a later stage.
Perhaps I'm confused because earlier versions of Debian had in the  
expert install mode a menu item "detect network hardware" which didn't  
worked sometimes. I realized that this menu item does no longer exist  
on Wheezy.

So this was my mistake; the problem which I have reported isn't one :-).
