You have a good point about qemu. One of the reasons I created the
Ubuntu 12.04 Server VM was to get a newer version of qemu-user-static.

Well, that's not what I need. I need to rebuild the kernel.
I'm just going to chroot into a copy of the root file system that I
got from the image I downloaded from here:
http://www.omappedia.com/wiki/Ubuntu_Pre-Built_Binaries
That way, I can just install the linux-source package,
build-essential, and whatever else I need in a self-contained
environment.
I originally started looking at the Linaro stuff because the
armhf+omap4 Ubuntu image runs very slowly, even after installing the
PowerSVG binary driver.
However, when I loaded the 12.05 and 12.06 Linaro Ubuntu images, all
I got was a black screen with a mouse pointer.
After running some experiments here, I discovered that the Linaro
Ubuntu images only work with displays that have a native resolution
of 1920x1080.
I tried to use kernel command line arguments to force the resolution
to work with my 1680x1050 monitor, but my changes had no effect. I
wanted to look at the kernel source for the Linaro Ubuntu image
because I can probably figure out the correct kernel command line
arguments from that. However, I could not figure out which git tree
to use.
The whole thing reminds me of the line from Zork: "You are in a
maze of twisty little passages, all alike."
