That's the problem. It appears that simply open-dev and assigning
my-self isn't enough. my-space (and my-address and my-unit) aren't
getting set up, so all config-space accesses are going to do the wrong
thing (they'll go to device 0, which may or may not be the root).

In the Sun/Oracle version, select would properly set things up, it
appears no equivalent is available under openbios.

I think you'll have to further debug this by getting the FCode to be
pulled in at startup in place of the built-in vga fcode, rather than
trying to fiddle things this way.
