Karmic A-6 Errors on boot

[Roy]

Karmic Alpha 6 boot error messages-
unknown key 'SYMLINK{unique}' in /lib/udev/rules.d/50-udev-default.rules:3
unknown key 'SYMLINK{unique}' in /lib/udev/rules.d/50-udev-default.rules:4

The lines in question-
3: -- SUBSYSTEM=="block", SYMLINK{unique}+="block/%M:%m"
4: -- SUBSYSTEM!="block", SYMLINK{unique}+="char/%M:%m"

udev[1045] NAME="%k" is superfluous and breaks kernel supplied names, please remove from
/lib/udev/rules.d/40-ppc.rules:3 :4 :5
I removed NAME="%k" from these lines and the error messages ceased but I didn't notice any other change.

can not read '/etc/udev/rules.d/z60_hdparm.rules'
This is a reference to a broken link ->../hdparm.rules (the file hdparm.rules does not exist)
According to the README in /etc/udev/rules.d this directory should not have SYMLINKS

There was some doubt expressed about the hard drive I was using for the Karmic install, so just to be sure I bought another drive and installed Karmic on it. All the errors that were originally there are still there and unfortunately I can't keep Karmic running long enough to do any useful testing. Whenever I try to do anything in a graphical window I get a desktop freeze within 15 seconds to a minute, and almost always if I try to save any changes. The terminal window *usually* lasts a little longer, but not more than 2 or 3 minutes if I am actually doing something in that window.
