lwip and seL4

[Steven Harp]

Observed a problem testing lwip under seL4 (run/lwip). 
This succeeds with kernels okl4, foc, and nova, but under
seL4 there are complaints from acpi_drv (see below).
The "Error: I/O memory [1ffe1000,1ffe2000) not available"
seems most concerning.

Build architecture is x86_32, relying on drivers dde_ipxe,
testing in qemu on Xenial.  Theories / workarounds (seL4)?
