freebsd stable - Jan 2007 - 6.2 & nvidia x11 driver: weird 16bpp/24bpp colorspace damage

Hi!

I've just upgraded to 6.2 and found terrible bugs with nvidia x11
driver. Everything works (i.e. X starts, opengl works, no errors), but
all colors are damaged terribly. It feels like graphics card is in 16
bpp mode, but X server thinks that it's in 24/32 bpp mode. Thus, value
of blue channel is completely ignored. I use same driver version that
I've used on 6.1, and I've recompiled driver with new kernel. I've
also
tried to recompile everything several time, tried bot nvidia and FreeBSD
agp drivers, but nothing helped. nv driver shows correct colors, btw.

Here's some additional info:

# pkg_info | grep nvidia-driver
nvidia-driver-1.0.9631_1

(I can't try latest 97xx driver, as it says my GPU is no longer
supported and I should stay with 96xx)

Update: after some research I've determined natre of this color
distortion. It seems like card interpretes each RGB8 value (24 bits, 8
for each color component) as RBG4 (12 bits, 4 bits for each component,
red-blue-green order).

Thus, color which is 0xFF0000 (red) looks like magenta onscreen (red 0xF, green
= 0x0, blue = 0xF) and so on.

Doesn't anyone have any problems with nvidia driver on 6.2-RELEASE?

Yes but my problem with the nvidia driver is because the
new version in ports no longer supports the card in my laptop
(GForce4 440 go).  X log says to use the old 96xx version of
the driver.

Wishful thinking: Too bad there isn't an nvidia-driver-legacy port.

Well, I've temporary solved a problem. I've downgraded to 6.1, but then
I discovered that nvidia 9631 gives artifacts on 6.1 as well. So I've
also downgraded driver to 8776 and voila - now everything works (so I
was mistaken - I've used 8776, not 9631 before system upgrade).

But the problem is still there - 8776 doesn't work under 6.2
(NVRM: agp_find_device failed, chipset unsupported?).
