I don't see Stephen's LCD problems, but I don't see clear text on my Seaboard T20-A03 dev system LCD, either. The text is blurred / almost unreadable, especially the last line (cmd prompt). I don't know if it's the scrolling change or the cache change, as previous incarnations (in the Google repo, at least) were just fine. Power-cycling doesn't fix it. I didn't test Ventana or Harmony. Please update the patchset so it (a) applies to u-boot-tegra/master and/or /next, and (b) fixes the text corruption on the LCD.
