Maybe efi_ioremap() is what needs fixing? I should mention this is a regression. 2.6.26 worked, 2.6.27 does not, and seems like things stopped working in 2.6.26-git1. I will check to see if efi_ioremap() used to be called with a 2.6.26 kernel on this hardware and see where the mapped addresses were. Maybe I can verify efi_ioremap() is actually broken. Brian
