I use genkernel.  To get my sound card to work the first time I had to
reboot with the LiveCD (Gentoo 2005), mount my partitions, chroot to the
new environmeny, etc, unmerge gentoo-sources and alsa-driver, completely
delete the directories under /usr/src and /lib/modules, remerge
gentoo-sources, zcat /proc/config.gz
> /usr/share/genkernel/x86/kernel-2.6 and run genkernel --all and then
reboot into my regular environment and emerge alsa-driver then
restart /etc/init.d/alsasound.  Yesterday I did everything I did
originally to get the sound to work and it doesn't.  I'm not sure the
kernel config was really clean.  What would I have to do to get the
original kernel config for when one first installs Gentoo?
