A note:
This is *not* enough to bring us to parity with Windows with these
adapters. There's also something wrong with our HPD handling that trips them
up - I suspect, based on AUX traces from one that's happy, that it's our
handling of short HPDs that's imperfect, as the device does a short HPD
Older DisplayPort to DVI-D Dual Link adapters designed by Bizlink have bugs
in their I2C over AUX implementation (fixed in newer revisions). They work
fine with Windows, but fail with Linux.
It turns out that they cannot keep an I2C transaction open unless the
previous read was 16 bytes; shorter
