(loged into kde but I have not done # udevstart as of yet):

lrwxrwxrwx  1 root root 9 Dec 18 03:45 /dev/dsp -> sound/dsp 

After doing # udevstart:
$ sudo udevstart
ernie@MRK ~ $ ls -l /dev/dsp
lrwxrwxrwx  1 root root 9 Dec 18 09:02 /dev/dsp -> sound/dsp


Looks the same to me, but I seem to have permissions for /dev/dsp Saytime 
works now, it didn't give me audio befor udevstart. Look at the times wierd 
huh?
Now, before logging into KDE:
lrwxrwxrwx Time is still odd

Not a good idea there. A device node for my nvidia graphics card was not 
created. I edited xorg.conf, changing driver from nvidia to "nv" just to get 
X up and running
Gotta recreate them. I guess. OK created the nvidia devices like so:

mknod -m 660 /dev/nvidia0 c 195 0
mknod -m 660 /dev/nvidia1 c 195 1
mknod -m 660 /dev/nvidiactl c 195 255
And changed back to TARBALL="on"
Let's see
 changed back to "nvidia" and rebooted. X working properly.

I don't see "Starting udevd" but I do see:
Configuring System to use udev
setting /sbin/udevsend as hotplug agent
mounting devpts at /dev/pts....
