<pre>I guess we'll need a better check at i9xx_enable_pll(). I don't know what kind
of frankenstein the machine is, but our driver thinks mobile chips always have
a panel, but the dmi quirk says it doesn't.
/* PLL is protected by panel, make sure we can write it */
if (IS_MOBILE(dev) && !IS_I830(dev))
assert_panel_unlocked(dev_priv, crtc->pipe);</pre>
