Default Weird color damage with 9631 after upgrade to 6.2-RELEASE

I've just upgraded to FreeBSD 6.2-RELEASE, and now I'm experiencing some weird problems with nvidia driver (9631). I've used the same version on FreeBSD 6.1 without any problems, but now after updating (and recompiling driver as well) I experience following: though everything works (no crashes, no errors, opengl works etc.), all colors are strangely distorted. It feels like 24 bit color value for every pixel is written to 16-bit value somehow. Thus, value for pixel's blue channel is ignored completely (tested in GIMP's color picker), though there are blue colors on screen. black->red gradient looks like many repeated gradiends of red->green.
Older versions of the driver stopped working at all (agp_find_device failed: chipset unsupported on the console). I've tried both FreeBSD and NVIDIA AGP drivers, VM86 interface for video BIOS calls, recompiled Xorg, but nothing helped.

Here's some info. May also post Xorg logs if needed.

GPU is ABit Siluro Gf3 (GeForce3).
