yes. The main question is about the use of the ioctl to propagate
the SMS ATN event to the host. I think this is probably the best
method but as this is a user API, we should be careful with what we
merge. I don't know any other implementation of a IPMI BT driver 
for the BMC side. 

Also, the drivers should probably be under char/ipmi. I will change
that.  

Finaly, the device name should contain "ipmi" IMO. Let's find a
name ! or a pattern at least.

Thanks,

C.
