Hi,
thanks to your explanations I think that now the situation is a bit more clear for me.
The problem is not related to a wrong version of "snd-hda-intel.ko". I am able to correctly compile and load the custom module provided with the hsfmodem package.
There are two cases:
1) Unfortunately, when the custom module (and it's brother "snd-hda-codec.ko") is loaded, I don't see any codec#1 device, so the modem isn't detected.
2) When I use the default gentoo-kernel module "snd-hda-intel.ko" (which doesn't need "snd-hda-codec.ko"), I can access codec#1 but hsfconfig still doesn't detect anything.
The latest "hsfdiag.txt" I've sent to you is related to this test case, where I've renamed the custom module "/lib/modules/2.6.25-gentoo-r6/updates/snd-hda-intel.ko" into "snd-hda-intel.ko.HSFORIG" and copied here (into "updates" directory) the original gentoo-kernel module ("snd-hda-intel.ko", 685433 bytes).
For the first case, as you said before, I suppose the problem is because the functionality provided by the replacement module "is no longer being maintained, because of many technical issues. Basically, this feature no longer works on some 2.6.25 and will not work on 2.6.26 and future kernels". So that module is outdated or at least not functioning properly with my 2.6.25 kernel. I've just installed a brand new 2.6.26 kernel for testing and I confirm that in this scenario the module even fails to build.
For the second case, I think the "only" problem is that the default alsa in-kernel driver lacks that little but essential alsa-driver patch. It seems that the only way to go is the first you told me, using the latest external alsa-driver-1.0.17 plus linuxant's patch.
Given that, now there's the problem with Gentoo's policy to maintain only the in-kernel alsa driver, which on 2.6.25-r6 kernel is 1.0.16rc2 release. So, if I've understood all correctly and you don't have any other suggestions, I may involve in this (or a separate) discussion the Gentoo ALSA team, as you wish.
Finally, some other questions come to my mind:
- Is the alsa-driver patch available only for the 1.0.17 release of alsa-driver or is there a version for older releases? In Gentoo's masked software repository there's an external alsa-driver package which I can test, but it's 1.0.16 release, so the actual patch shouldn't be appropriate.
- How can I know which alsa release is shipped within a particular kernel version before actually installing the kernel?
- I still don't understand *who* refused linuxant's patch submission and why?
Thanks,
Marco

Since with the original gentoo snd-hda-intel.ko kernel module the modem seems to be recognized (codec#1 is present), I've replaced the module created by hsfconfig into "/lib/modules/2.6.25-gentoo-r6/updates" with the original version and rebooted the system.

This guide will focus solely on configuring ALSA via the in-kernel driver.
