When "Xorg -configure" doesn't produce a usable configuration

My configuration happens to be an HP pavilion zx5000 with Nvidia
x10de/0x0179 (GeForce4 440 64Mb).
This machine has "widescreen LCD" that claims up to 1900x1440.
I've been comparing behaviours of Xsun and Xorg on Solaris.
I'm starting to think that the 0x0179 or its BIOS has some fundamental
differences from other Nvidia products
that require special casing. In particular, I have a desktop box with
0x0188 (Quadra4 AGP) that is much more
stable and usable. Perhaps a lot of the low level control is well
handled in the TwinView binaries, but I need to
show this working in the open source ddx.
Particular problems include:
analog output syncs differently from LCD, and management of the 2 is not
obvious. Have to ask HP about
hotkey or other.
Xorg -configure output does not sync up the LCD. It registers at
1280x1024, but no joy. After a cold reboot,
the screen comes up at 640x480
When the X server exits, it leaves the LCD unsynced. Occasionally, the
analog out is synced ok. This happens
even when it was at 640x480.
I would appreciate a pointer to hand-tuning the config file.
I expect the dual screen and on-exit problems will require work in the
ddx and perhaps driver.
Is there a proc in the ddx to int11 or otherwise tweak the chip into low
Mark: apologies for the direct message if you've moved on from our
little X world.
Who do we have at Xorg with some experience inside the o.s. nvidia ddx's?
