OK, I check and both are selected for 'AUTO'.

Well, I went and build a new 2.6.11-gentoo-r11 kernel, selecting
everything for sound as a module:
device drivers-->sound
<M> Sound card support
--> ALSA
<M> Advanced Linux Sound Architecture

mine looks like this:
CONFIG_SND=m
CONFIG_SND_TIMER=m
CONFIG_SND_PCM=m
CONFIG_SND_RAWMIDI=m
CONFIG_SND_SEQUENCER=m
# CONFIG_SND_SEQ_DUMMY is not set
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=m
CONFIG_SND_PCM_OSS=m
# CONFIG_SND_SEQUENCER_OSS is not set
# CONFIG_SND_VERBOSE_PRINTK is not set
# CONFIG_SND_DEBUG is not set

For now I'd just like to get the basic sound working. (I.E. ignore
5.1 audio for now.) I have 2 identical systems. I'm trying to get
ALSA working on the one without the LML framegrabber board now.
What puzzles me now is when I try to run (from the web page
http://www.gentoo.org/doc/en/alsa-guide.xml#alsa-utilities)
'emerge alsa-driver' I get this error message:
<snip>
* Determining the location of the kernel source code
* Found kernel source directory:

* Found sources for kernel version:

* Checking for suitable kernel configuration options
* ALSA is already compiled into the kernel.
* Please check to make sure these options are set correctly.

!!! Incorrect kernel configuration options
!!! If you need support, post the topmost build error, NOT this status message.
Now remember form above, everything under sound is a <m> module.
