trivial notes:

Try breaking up the patches you send into more discrete
chucks that do just one thing, not mostly one thing
and some other things.

It may be better to use a temporary for brd like:

struct dgnc_board *bd = dgnc_Board[brd];

as is done a few other places.

so this becomes
di.info->physsize = bd->membase - bd->membase_end;

though I wonder if this is a defect and size
should be bd->membase_end - bd->membase + 1

It doesn't need a cast as membase and membase_end
are ulong already.

It also seems this physsize variable isn't used.

That's less attractive then what's already there.
The generic kernel form for an array declaration would be:

static uint dgnc_offset_table[8] = {
0x01, 0x02, 0x04, 0x08, 0x10, 0x20, 0x40, 0x80
};

This also would be better as static const.

I stopped reading here.
