Security of Mac Keychain, File Vault

The article at claims  
that both are easily broken.  I haven't been able to find any public  
analyses of Keychain, even though the software is open-source so it's  
relatively easy to check.  I ran across an analysis of File Vault not  
long ago which pointed out some fairly minor nits, but basically  
claimed it did what it set out to do.

The article makes a bunch of other claims which aren't obviously  

Anyone one know of more recent analysis of Mac encryption stuff?  (OS  
bugs/security holes are a whole other story....)
