Yeah it's something to do with the scsi/sata drivers now handling IDE 
devices, it caused me some grief at first because I used to hot-swap my 
laptop drives with a KDE utility which stopped working (I since found 
the /sys/class tree which I can use to add and remove controllers). But 
my desktop still has /dev/hd* devices and it's running the exact same 
Ubuntu kernel as my lappy. I don't really understand but as long as it 
works I'm happy :-)
