Hmmm, so this is a LinuxCNC install?  Will you actually be 
running LinuxCNC on this?  (Real time and laptops don't 
coexist all that well, although the trouble USUALLY only 
starts when you try to run actual real time stuff.)

One of the big problems is that laptops do all sorts of 
system management stuff in the machine BIOS, such as battery 
management, thermal management, emergency shutdown upon low 
battery or CPU overheat, etc.
Running RT OS's can disable part of these features on 
certain machines.

Right now, I'm running Ubuntu 12.04 (without the rtai 
option) on a few laptops, and it seems to work pretty well.

One thing you can do is a Google search on the specific 
version of Debian and the laptop model, and see if there are 
known problems. I'm not clear, but it seems you say that if 
you use the recovery boot and start X manually, then it is 
stable.  So, that may mean that either X is starting at the 
wrong time, before something else is ready for it, or that 
somehow the manual start brings up a different X 
configuration that works better.  Possibly the graphics 
driver that is used is different in the two cases, lots of 
machines are sensitive to which graphics driver is used, and 
there are some different drivers that can use less 
accelerated graphics features and may be more reliable.

If you give me some more specific info that "your dad's 
laptop" I might be able to dig up something pertinent.
