Ideally this would have been something that just showed up in an option-rom bar on the device, but that did not happen so it is left to software. For legacy-bios we scan adapter rom space looking for our table, for efi it's comparatively cleaner we just grab this efi variable identified by its own GUID.
In the worse case a late merged icsi driver just wouldn't support EFI-based boards out ot the box until 2.6.40. I don't think that is too much of an issue.
