The problem is that this is a rapidly moving target and old 
documentation never goes away.  A few kernel revs back your IDE devices 
would have been named /dev/hdX with fixed controller/drive select 
mapping to a/b/c/d for the X.  Now everything gets named dynamically in 
the order detected.   I think the idea is to accommodate hotplug devices 
more cleanly, but it comes at the expense of making the devices that 
could have predictable names as confusing as the ones that can't.
