Version 2 of the Linux IPMI driver

I've cleaned a few things up and fixed some minor bugs. The only big change is renaming the "unused" address to the "system interface" address (which makes a heck of a lot more sense). I'm working on userland tools that will tie in to this and to LAN/ICMB stuff, and there I saw the need for the name. I still haven't tested interrupt-driven operation, but that's really a rather minor concern since almost no boards support it and the driver will work without it.

You can get the patch on my web page at http://home.attbi.com/~minyard, relative to 2.5.33 or 2.4.19. The patch is fairly self-contained, so it should be easy to port to other kernel versions.

The lanana guy is not available for a while, so I'm not getting a device number in the near future, but I think it's ready for the 2.5 release. Does this need more time, or is it ready for inclusion?
