Does anyone see what this might be?
What's the value on CONFIG_FB_CFB_REV_PIXELS_IN_BYTE in your .config?
$ zgrep CONFIG_FB_CFB_REV_PIXELS_IN_BYTE /proc/config.gz
# CONFIG_FB_CFB_REV_PIXELS_IN_BYTE is not set
Does your driver set FB_NONSTD_REV_PIX_IN_B?
No it doesn't. I also tried setting it now, with no effect:
info->var.nonstd = FB_NONSTD_REV_PIX_IN_B;
