[Openchrome-devel] Getting ready to release OpenChrome Version 0.3.4

I have access to a Quanta IL1 compatible netbook, which is VX800-based. 
It has a 800x480 LCD display and a VGA output.

I can confirm that the display does not come back after suspend (usually 
off, sometimes it turns on and fades to white). Also, on my system, 
Openchrome does not support dualscreen (not enough Xrandr support).

If you do some VX800-related changes, I could test them.

About KMS... if it is working correctly, then the Modesetting driver 
should work fine. What further benefits would the Openchrome X driver 
provide on VX800 or newer chipsets? Since 3D and video decoding will 
probably never be implemented, a KMS driver with xf86-video-modesetting 
alone could work well.

Best Regards,

> I recently fixed a bug related to probing for VT1632A with the person who reported it, and since I do not own a regular computer that has DVI (I do own 2 thin clients with VT1632A, but have not had to time to figure out how to use them.), I want other people to do the testing to see if the latest fix works for everybody.
> I am also working on trying to fix VGA coming out of s DVI-I connector via DVI to VGA dongle, and this is also related to the VT1632A probing issue.
> With the latest fix, VT1632A is being probed for every VIA Technologies chipset (previously only for P4M800 Pro / VN800 / CN700 chipsets) via I2C buses, and as far as I am concerned, this new code path works well with KM400, K8M800, VN896, and P4M900.
