Well, technically you aren't writing to kernel text space, you are
writing to low real memory locations. :-)  I've done several PowerPC XIP
from rom systems without any trouble, so I kind of fail to understand
why this would cause trouble.  I don't know what we gain from XIP,
except a little available ram space, but it people want it.....
