Skeleton / Example PCI Device Driver

[John J. Karcher]

Hello,

In my slow quest to port/write the VirtualBox Guest Additions, the first 
step is a driver for the virtual PCI device that handles communication 
with the VirtualBox host.

Is there a skeleton device driver for PCI devices?  My first goal is 
just the boilerplate init code, attaching to the IRQ and I/O memory, and 
logging the interrupts as they come in.

If there isn't a skeleton driver, could anyone recommend the simplest 
example that I could use as a starting point?

  Thanks!
