How many pcdisplay at isa can there be one machine?
Iirc, this code is originating from alpha where you can have
multiple independant PCI/ISA/EISA hierarchies and thus
multiple pcdisplay/ega/vga devices.
Can the two tags that pcdisplay_is_console() compared ever come

Let us add a bus_space_is_equal(bus_space_tag_t t1, bus_space_tag_t
t2) for implementation in MD code
That's generally OK. (We have this in pthread_equal().)
return memcpy(t1, t2, sizeof(t1)) == 0;
That will work even if bus_space_tag_t is a struct.
I hope you
