I have something written, but I don't seem to recall even compiling it.

What happened was that our motherboard (Which actually has an SMBus header on it 
to hook dohickeys up to) seems to have the SMBus controller disabled (it doesn't 
show up in lspci or anywhere, and nothign seems to be able to identify 
anything), so we scratched our plans to use the PCA9555.

I can provide the driver to you if you like, but again, I can't guarantee that 
it will even compile (however, if it doesn't, the fixes are probably just minor 
things like syntax errors).  I think I have everything down to where it should 
be pretty easy to get working.

If you would like the file, just reply and I'll forward the source on to you.
