SeaBIOS only supports 512 byte sectors for floppies/harddrives and only supports 2048 byte sectors for cdroms. I suppose one could implement an emulation layer (similar to the way the "El Torito" spec can make a cdrom look like a harddrive), but so far nothing has required that.
I suspect future drives will boot in a legacy mode that uses a 512 byte block interface - exactly because of these types of issues.
