New Revision: 221330
URL: http://svn.freebsd.org/changeset/base/221330

Log:
  As it happens, interrupts actually do work. The problem is that
  bge(4) in this case is simply not asserting an interrupt. I
  suspect that this is due to DMA not working. A non-DMA device
  that generates interrupts (A 3D graphics card, programmed to
  interrupt on DDC events in this particular case) proofs that
  interrupts work.
  
  With this out of the way, what's left to do is:
  1.  IPIs (fairly trivial)
  2.  DMA (rather involved)
