If 7.0 will not boot, it might be due to APIC/atpic

'device atpic' was removed from the 7.0 amd64 GENERIC kernel,
which on my board resulted in lots of problems like:

     Could not allocate irq
     unable to allocate interrupt
     attach returned 6

and a failure to boot.  I added atpic back in and it boots.
(I'm not saying this is the only or best fix, simply *a* fix
that worked for me.)
