The Short story... it was a dark and rainy night :-P oops, wrong mailing 
list.... so here goes

The kernel boots and when init.d starts, the screen switches off, the 
CPU fan goes to Max speed, and a few minutes later all goes quiet and it 
appears to have powered off.

I usually boot with noapictimer and if I disable ACPI totally, the clock 
references don't work and the timebase goes wrong. (Playing a MP3 is 
quite an entertaining event as it sounds like an old vinyl record player 
with a slipping drive belt)
