Comment(by umccullough):

 I tested R1/Alpha1 on my wife's ASUS desktop computer which has an i915
 chipset, and after the boot screen logos are all lit, the screen goes
 black for a second, and then comes back with a shifted image of the boot
 screen with some artifacts at the bottom corner at which point it hangs.

 This is booting from USB stick, btw, the screen is a 1920x1200 LCD
 attached to the VGA port (no DVI port on this box), machine has 2gb RAM.

 I can get into KDL from this point - but the KDL output is also shifted
 and wraps around the screen slightly, it seems the framebuffer alignment
 is all screwed up at this point.

 I tried a somewhat newer revision (from last week I believe), but it keeps
 hanging at the disk icon (the R1/Alpha1 did this one one of the boot
 attempts also). I'll try an even newer one soon.

 If I set fail safe video mode, R1/Alpha1 boots to a desktop just fine.

 What can I provide that might help? I can hook a serial cable to the
 machine if necessary, or take photos of the screen state if necessary.
