Hi Eric,
  Recently, i've been trying to confirm this bug on Wyse V90LE. I installed
Lubuntu-12.04-desktop with the default kernel 3.2.0-23-generic. The monitor is
G225HQV (DVI to VGA). I've tried some version of ddx(including revision 8bc53d8
and revision d951436 in your logs). In older versions before revision
7a98f65(Using I2C bus 2 to detect a VGA monitor), VGA doesn't work. But in
later versions(like release 0.4.0), VGA works and cursor shows up. Then i added
some debug info in some functions to print the register value of Hardware
Icon(VIAGETREG(PRIM_HI_POSSTART)). And it turns out that HWCursor works fine.
