As Johann works on the named address space implementation in GCC, I
think he really wants a true 24-bit data type. The overall goal is to
be able to eventually replace all those workarounds ("use only the first
64 KiB", "use a 32-bit number instead") by a genuine 24-bit addressing,
so you can write something like:
__farflash const char *stringtable[] = { ... };
and have the compiler insert the correct (ELPM) instruction to access
them when referencing "stringtable" data.

Never trust an operating system you don't have sources for. ;-)
