FWIW, I did find a set of MILO sources. Search for milo-2.2-18.tar.bz2;
it points to a variety of gentoo mirrors.
That version does not reference BOOT_PCB. I thought about removing this
define as well as a couple of other unused defines, but wanted to keep
the changes minimal.

On a side note, we may revive the parisc patch. Helge isn't entirely
happy with the other solution for parisc; it is quite invasive and
touches a total of 19 files if I counted correctly.
