Shouldn't acpi_ipmi_getresource() also look for IRQ descriptors? The existing code that looks at the SPMI table can handle either GPEs or regular IOxAPIC interrupts (i.e., a GSI). You might also want to look for memory address ranges as well as IO ranges. I wish you could use pnp_register_driver() instead of acpi_bus_register_driver(). That would let you get rid of all the _CRS parsing. But I forgot that IPMI devices often use GPEs instead of regular interrupts, and GPEs require a different path (acpi_install_gpe_handler() instead of request_irq(), etc), so I guess you're stuck with grubbing through _CRS by hand. Plus, it looks like you need the _IFT thing to figure out what type of interface it is. It might have been nicer if there were separate PNP IDs for KCS vs SMIC vs BT. But that's water under the bridge.
