problems with i865 on HP dc5000 (NetBSD, XFree86 4.4.0)

I've been unable to get XFree86 4.4.0 running on a NetBSD-current 
system running on an HP dc5000.  It complains that it can't find the 
right video modes; I *think* that there's a clue in this excerpt from 
the log file:

	(II) Loading sub module "ddc"
	(II) LoadModule: "ddc"
	(II) Loading /usr/X11R6/lib/modules/libddc.a

Using a FreeBSD Live CD -- with X 4.3.0, not 4.4.0 -- I get

A Knoppix CD gave similar correct results.

I also noticed that XFree86 -configure didn't read the
monitor characteristics -- again, this is done via ddc.
Again, that worked with FreeBSD Live or Knoppix.

>From the code, the problem is in the int10 calls.  Disabling
DDC or int10, via Options statements in the XF86Config file,
cause initialization failure messages.

I've put the X config file at 
http://www.machshav.com/~smb/x-problem/XF86Config (the monitor lines 
are taken from a Knoppix attempt); the full log file is at
http://www.machshav.com/~smb/x-problem/XFree86.0.log .  Any help would 
be appreciated.
