Just found this small snippet of a post on Asia's Finest and found it to be very informative about the word kha (I know I am little obsessed over Khmu-Tai relations and this word).
So what I imagine is that the Khmu people who got to escape got to live their lives the way they had for centuries (or simpler, they might've been town folks but had to revert back to living with nature due to the Tais taking the lowlands? just a theory) but they still had to pay tax and do corvey labor (whatever that means). For those who couldn't run away probably became direct slaves as in they were owned not "rented" and overtime became the Lao folks we know today. If this is true, then this guy on the forum's assumption that " to be Lao is to be Khmu and visa versa" is on spot. It kinda make sense because if you think about it, the Tai Lue in China look Chinese whereas the further you go down, they look more like Khmer and Khmu like which would probably mean that they mixed in with the locals. Anyways just my two cents and as usual my food for thought.
*I remember when me and Frank Proschan had conversation, he told me that the Lao did chase the Khmu out of Luang Prabang into Luang Namtha
