Try to do the same with the _E macro. Be creative :)

with this patch it gets past this crash and seems to boot and then run
into some i2c devices that are not emulated by QEMU yet:

Does anyone know what these could be? (MorphOS seems to care about two I2C
busses mapped at 0x80018000-0x80018fff (Keywest) and 0xf8001000-0xf8001fff
(Uninorth).)
