LinuxQuestions.org - getting sound modules to work on a Thinkpad T20 with a custom 2.6.10 kernel

Behold my |\|00|3n355. I configured and installed a 2.6.10 kernel and everything works fine. Except for the sound that is. The kernel is configured to load the alsa stuff as modules (I left oss out). At the end of dmesg I see the following error:

Code:

(...)

cs46xx: failure waiting for FIFO command to complete

NET: Registered protocol family 17

Generic RTC Driver v1.07

When I check lspci I get:

Code:

(...)

0000:00:05.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator] (rev 01)

(...)

and lsmod gives me this:

Code:

snd_pcm_oss            48996  0 

snd_mixer_oss          17728  1 snd_pcm_oss

genrtc                  8116  0 

af_packet              13192  2 

snd_cs46xx            82568  0 

snd_rawmidi            19872  1 snd_cs46xx

snd_seq_device          6796  1 snd_rawmidi

snd_ac97_codec        73728  1 snd_cs46xx

snd_pcm                85288  3 snd_pcm_oss,snd_cs46xx,snd_ac97_codec

snd_timer              21316  1 snd_pcm

snd                    45764  8 snd_pcm_oss,snd_mixer_oss,snd_cs46xx,snd_rawmidi,snd_seq_device,snd_ac97_codec,snd_pcm,snd_timer

soundcore              7328  1 snd

snd_page_alloc          7524  2 snd_cs46xx,snd_pcm

(...)

which seems fine, but when I check dmesg again it now also gives an IRQ error:

Code:

(...)

cs46xx: failure waiting for FIFO command to complete

NET: Registered protocol family 17

Generic RTC Driver v1.07

spurious 8259A interrupt: IRQ7.

Anyway, I might have found solution here: main.linuxfocus.org/~guido/gentoo-tpt20/.
It involves adding the line "options snd-cs46xx thinkpad=1 index=0" to /etc/modules.d/alsa. But that is in Gentoo. Debian does things differently. So (I guess) my question is, where the hell in Debian is the alsa kernel module (config) file located so that I can try adding said line? Or if anyone knows of a different remedy, please tell me...
