Comment # 10 on bug 1209155 from Takashi Iwai

Might this because of some screen rotation?  The size truncation to 135x135
sounds weird.  135 * 16 = 2160, and it implies that the kernel detected the
initial width to be 2160 by some reason, and keeps the size as is.

In anyway, please give the full dmesg output and the hwinfo output -- supposing
that the problem still persists with the latest TW kernel.
