EBDA is safe to use during lilo and grub as part of a BIOS. As long as the EBDA is properly formed.
However, it is considered 'bad behavior' to allocate much more than 4k of EBDA as we find others (not Linux) that depend on the 640K region of memory run out of this precious resource. Beware of several add-in BIOSii that each allocate EBDA; nest/size/relocate/offset properly.

Is this handled for 2.4/2.6 Kernels? Reason I ask is we are considering having BIOS(for a SCSI HBA Controller) allocating memory in EBDA for Firmware use. We are concerned whether Linux would be writing over this region of memory during the handoff of BIOS to scsi lower layer driver loading.
