Subject: occasional glitches with 2.6.36+

Over the past couple months I've noticed a couple problems that don't always 
happen.

First, the framebuffer (intel gfx) thinks its about 1/4 the size it really is, 
even after logging in.

Second, my sdhci device likes to error out:
[    1.615309] irq 17: nobody cared (try booting with the "irqpoll" option)
[    1.615365] Pid: 0, comm: kworker/0:0 Not tainted 2.6.36-nofp #25

[    1.616306] Disabling IRQ #17

Neither of these always happen. I've tested with memtest86+ a couple times, 
nothing so far.

But they both seem to happen at the same time.
