We can just make the ACPI range statically a page bigger. It's no big loss
(consider that we squander >100kB of memory between 0xC0000 and 0xF0000
right now), and at some point in the near future we'll get rid of the acpi
option and always produce ACPI tables. There are just a few interrupt issues
to sort out first.

The printk patch could be useful, however, since hvmloader is going to get
more complicated in other ways and we'll want to get tracing out of it.
