I've been told that loading Linux at that high an offset from the memory
base wouldn't work after all, even on bare metal. I therefore set
kernel_addr_r to 0x80008000, which makes Xen load DOM0 at 0x8fc00000. I
can see Linux starting to boot from this address on bare metal, but With
Xen I'm seeing "uncompression error" (not printed on to the console, but
through debugger inspection).

I haven't pinned down why exactly it's throwing this. While I'm at it,
I'd appreciate any helpful pointers.
