Sound on IBM ThinkPad 600E with Fedora 7

[juhani....@kolumbus.fi]

Has anybody got sound working on a 600E with Fedora 7 (or FC6)? The
problem with 600E is that its sound card is mis-detected as snd-cs46xx
which it is not - see the links below for explanation.

I have tried for a long time to get sound working on 600E with Fedora
7. I have followed instructions from the following links, although
they are for SUSE and Ubuntu:

My modprobe.conf is as follows:

alias char-major-116 snd
alias snd-card-0 snd-cs4236
options snd-cs4236 id=first port=0x530 cport=0x538 isapnp=0
mpu_port=-1 fm_port=0x388 irq=5 dma1=1 dma2=0

alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

alias sound-service-0-0 snd-mixer oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

And in /etc/modprobe.d/blacklist there is a line:

blacklist snd_cs46xx

Now when I issue command "modprobe snd-cs4236" the console floods with
messages:

CS4236+ soundcard not found or device busy

lspci -v shows:

...
00:06.0 Multimedia audio controller: Cirrus Logic CS 4610/11

Here IRQ is 9 but everybody else suggests that I should use irq=5 in
modprobe.conf. Is this a problem?

Contrary to what was suggested in http://www.litljay.com/howtos/600e/
I initialized the BIOS, and then disabled Quick Boot. After that the
sound started working!
