Have pushed a series of changes that should (hopefully) fix this. We now use 16-bit protected mode for access to high memory during decompression. Tested in bochs, qemu and kvm, but would appreciate reports for other hypervisors (especially VirtualBox). (As a nice side-benefit, iPXE now starts instantaneously in kvm, rather than taking a second or so as kvm hammers its way through hundred of thousands of vmexits.)
