ddi_regs_map_setup() only maps what the "reg" property contains. Have you set
"regs" in your .conf file? See driver.conf(4) file for details and examples.

Instead of creating a node, you could install your driver as a pseudo driver,
by creating a /kernel/drv/ipmi_lpc.conf (or whatever's you driver name) file
containing the line:
name="ipmi_lpc" parent="pseudo" instance=0;
The system will load the driver even if there isn't a hardware node for it.
