Hi John,

  Okay, actually this driver is what I am now investigating with(compared to
current drm-openchrome KMS driver). But mine is a little different from yours
because mine only has source code files to compile via_chrome9.ko which is
under TTM folder. For other tow user drivers(via_drv.so and
via_chrome9_dri.so), there is no source files to compile them. 
  Then, I did further check on the website: 
   http://linux.via.com.tw/support/downloadFiles.action
  Finally I found the same driver as yours under this link when I select
"Lubuntu 15.04" as the OS and "VX900" as the platform. The driver includes not
only via_chrome9.ko source files, but also via_drv.so source files.
  Actually I have used this via open source driver verified VGA port on my T510
platform and see it can make VGA work properly and EDID information can be
probed out(not fake EDID information). Again, I am using a LCD monitor instead
of a CRT monitor.
  If you can wait for several days until my HP T5550 come, I think I can
provide you more help on this issue.

Thanks,
Frank
