The PCI-3.0 Firmware specification allows for option-roms to have 512-byte alignment rather than 2048-byte. As there does not appear to be a reliable method to detect a PCI-3.0 compliant BIOS from userspace we allow the imsm platform detection code to presume that a system modern enough to have an Intel AHCI controller does not have dangerous/legacy ISA regions in the option-ROM memory space. An environment variable to disable this behaviour, IMSM_SAFE_OROM_SCAN, is added in case this presumption is ever proven wrong.
