The set of patches that I am asking Linus to pull now can use the ACPI table 
to find the table or in the fallback case the old method of scanning the 
memory. However if the machine has UEFI it will only do ACPI table lookup.

Can you point me what 'standard ACPI mechanism' is? Like sticking the code in 
the drivers/acpi ? And then having a generic driver to handle the 
[i,a,s,m]BFT tables and maybe some subordinate ones for specific pieces where 
the generic can't handle it?

What is the tools state ? For iBFT, iscsi-initiator-utils scans 
the /sys/firmware directory to extract the relevant data and does its thing. 
Are there tools for AoE, SCSI RDMA Protocol (SRP), and in-memory disk?
