Try this first:

modprobe ipmi_msghandler
modprobe ipmi_si
modprobe ipmi_devintf

If you have IPMI hardware, those should succeed.  The udev rules should 
produce /dev/ipmi/0 when those modules are loaded, but if they don't, 
you can create the device file like so:

mknod /dev/ipmi0 c 254 0

Oh come on, computers never lie, so admit it: you're using liquid 
nitrogen to cool it.  Can I have some?
