I was afraid someone would say that. I've been having a look and a think
about the situation for x86, and I cannot come up with a sane way to
emulate the way the global data pointer is handled by the other arches.

I essence, the gd pointer is a unique global variable available prior to
relocation. On all other arches, this is achieved by using a reserved
register which I do not have the luxury of on x86 :(

Unless I can resolve this, I cannot move x86 in line with the other arches
(i.e. init functions can only be done after relocation).

I'll keep thinking about a possible solution
