Good.  I agree.

I think there are a couple of possible fixes depending on what the
real problem is.

If the problem is that it needs to be at a fixed address, allocate it
at the top (as high as you can before the IOAPIC) of the address
space, and mark it fixed.

I guess there are too many other possibilities for why you needed to
implement it that way, but I'd be happy to help you solve the problem.
