Actually, the best practice is to install your new drivers in /lib/modules/`uname -r`/updates/sound. depmod will automatically detect these as newer than the other modules. This is how I test new alsa builds on my test platforms.
The sound modules in linux-ubuntu-modules are modified from the stock version of alsa that comes with the kernel in Ubuntu. The patches are NOT for release into upstream alsa, as they have already been submitted and are in 1.0.16 and later (I know, I wrote them).

This just an FYI
In Ubuntu 8.04, ubuntu has packaged alsa-drivers including some out of tree drivers in a separate package: linux-ubuntu-modules-$kernelver
This gets installed in /lib/modules/$kernelver/ubuntu/sound
The only things installed in /lib/modules/$kernelver/sound are soundcore.ko and ac97_bus.ko
However, when you do a default "make install" from alsa-driver source, the modules get installed in /lib/modules/$kernelver/kernel/sound
So, now there are 2 copies of the drivers in different places.
I have taken to removing (moving away to say /root) /lib/modules/$kernelver/ubuntu/sound to avoid any confusion and some odd module versioning problems that I was having.
