Hi Kevin 

First, thanks for reassuming the development of this project. 

I have an HP-T5550 and I wonder if VGA connected to DVI-I port of T5550
supposed to work at current master (commit b8eb2ab)? I have built current
master and tested it but result is same as original openchrome 0.3.3. I am
attaching the log file. I donot know if they will be helpfull, but I have
enabled some register dump and I2C scanning options in xorg.conf. (Pls. see
head of the log file.) My SW platfom is a custom Linux mostly based on a
previous snapshot of Thinstation 5.2. 

I have performed tests with two different CRT monitors, two different DVI-I to
VGA adaptors and with a Y-cable (DVI-I to DVI and VGA). All have same logs
(except few bencmark differences). 

Both monitors work OK with recent via (semi ?) opensource KMS driver. You can
check it at
