Hi Jarod, it's been an interesting weekend.  The box is a bit twisted at 
the moment; I've reloaded MD-12 from scratch, run all the alsa-1.0.23 
updates (lib, lib-devel, util), , then "yum update", which did about 257 
packages.  Interesting though, it's still reporting the alsa version as 

[mythtv at vanson videos]$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.21.

Here it is before and after:

Before depmod -a:
[root at vanson ~]# modinfo snd

After depmod -a:
[root at vanson ~]# modinfo snd

...not sure this is what you meant, so I built and installed alsa-driver 
from source again.  I've wiped the box and re-installed MD-12 since the 
last build.

...then ran depmod:
[root at vanson alsa-driver-1.0.23]# modinfo snd

...then reboot and depmod -a again
[root at vanson ~]# modinfo snd

...now it sees the new version.
[root at vanson ~]# cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.23.
Compiled on Jul 25 2010 for kernel (SMP).
[root at vanson ~]#

Is it right?  Is depmod -a all I needed to do in the first place?
