I gave up on compiling the whole 2.6.14 kernel to get working Intel HDA
sound drivers, and instead compiled the sound drivers against the
headers in the installed 2.6.12 kernel. This meant fixing some
references to new 2.6.14 kernel functions (kzmalloc, kstrdup), which I
found and pasted into the driver code statically. Now I get sound and my
DVD-RW works splendidly. Thanks Wim.
I still don't know how to build a kernel from source identitical to the
kernel binary provided with the Debian netinstall. If anyone knows how
to do that, please let me know.

I have installed Debian Testing via the netinstall, and have a kernel
2.6.12-1-386 from Debian testing (etch). I'd like to make some changes
to the kernel source, namely the device driver for my sound chip. I
installed what I thought was the kernel source, and expected to see
"-1-386" in the source tree top-level Makefile's symbol for
"EXTRAVERSION". However, it's blank.
I built this kernel, booted from it, and had different behavior from the
one that came in binary form with the netinstall. The problem is with my
CD-DVD RW. With the default kernel, it appears fine as /dev/hda and
works with several apps. With my compiled kernel, it appears as
/dev/scd0 and doesn't work with several apps.
How can I get the actual kernel source used to build the binary kernel
installed with Debian netinstall? I expect the procedure to be this:
1. apt-get install kernel-source-something
2. cd /usr/src/kernel-source-something # verify Makefile has
EXTRAVERSION = -1-386, change to -1-386-custom
3. cp /boot/config-2.6.12-1-386 .config
4. make xconfig # just save and quit
5. make bzImage modules modules_install # verify
/lib/modules/2.6.12-1-386-custom
6. cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.12-1-386-custom
7. cp System.map /boot/System.map-2.6.12-1-386-custom
8. mkinitrd -o initrd.img 2.6.12-1-386-custom && cp initrd.img
/boot/initrd.img-2.6.12-1-386-custom
9. Edit /boot/grub/menu.lst, clone entry for default kernel
As I said, doing this I didn't see the telltale EXTRAVERSION = -1-386,
and when finished the kernel wasn't the same as far as /dev/hda
behaviour and some other things scrolling by on the boot console.
See if the module can be built against the kernel headers. There's a
package you can install (linux-headers-... I think, might still be
kernel-headers-... in sarge). This would be the way you can compile
extra modules. If that won't work and you still want an extra module
it would probably be easiest to just compile the entire kernel instea
