10.6.2 failed to install due to 'nfs error', audio no longer works

Question

macbook pro, all other updates have installed just fine, except for 10.6.2
I get this in the log:
11/10/09 3:58:15 PM com.apple.kextcache410 Created mkext archive //System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext.

nothing is mounted (i rebooted before applying). not sure why it's giving that NFS error. it's consistent tho.. if i reboot and try the manual install of the patch, I get the same error.
after the failed patch "installed" it left my sound not working... so far everything else appears to work. any thoughts on fixing this are appreciated. i ran diskutil and 'fixed perms' and 'verified disk' ... patch still fails.

Try reinstalling the patch. If you get all the way through the installation, then see if your sound works. If not, then I suggest you do a repair install of Sno by installing Sno over Sno as in an upgrade install. Such an install, while usually very safe, still is an install so be appropriated backed up if you proceed.
