I see this in the dmesg, [ 0.000000] efi: skipping setup_data on EFI 32BIT! despite the fact that this is on an x86-64 box. Turns out it's because CONFIG_DEBUG_BOOT_PARAMS isn't set in my config. You may want to turn that on automatically. After doing that things work on my ASUS box (good work!) but the SATA controller craps out on my Tunnelmountain machine, but that's probably unrelated and I'll debug that separately. I see a bunch of section mismatch warnings, WARNING: arch/x86/platform/efi/built-in.o(.text+0xd1e): Section mismatch in reference from the function efi_map_regions_fixed() to the function .init.text:efi_map_region_fixed() The function efi_map_regions_fixed() references the function __init efi_map_region_fixed().
