sarge, kernel 2.6.12.3, and sound

[Steven Pasternak <stevenp500@bellsouth.net>]

Hi! I have sarge, with kernel 2.4.27-2-k7. I upgraded to a 2.6.12.3 
using sarge's 2.6.8 config, but now I don't have sound. /dev/{dsp,mixer} 
are gone. I have the "use OSS API" set under "Device 
Drivers->Sound->Advanced Linux Sound Architecture" Is that bad? I 
installed alsa-base and alsa-utils and ran '/etc/init.d/alsa start', but 
still no devices. What's up? Thanks!
