Started a bisect of the lucid kernel for testing, notes below.

Created a lucid i386 schroot for building kernels on my x86_64 natty system 
using the kernel team build scripts: 
https://wiki.ubuntu.com/KernelTeam/KernelMaintenanceStarter 

Kernel bisections (https://wiki.ubuntu.com/Kernel/KernelBisection): 
$ git clone git://kernel.ubuntu.com/ubuntu/ubuntu-lucid.git 

Commit tags for good and bad kernel: 
Bad: Ubuntu-2.6.32-32.62 
Good: Ubuntu-2.6.32-31.61 

All commits between the two releases we think are "good" and "bad": 
$ git log --oneline Ubuntu-2.6.32-31.61..Ubuntu-2.6.32-32.62 > 
../diff-Ubuntu-2.6.32-31.61-Ubuntu-2.6.32-32.62 

$ git log --oneline Ubuntu-2.6.32-31.61..Ubuntu-2.6.32-32.62 | wc -l 
179 

179 commits between the two tags.

Checkout a tree with all commits up to the "bad" kernel tag, 
Ubuntu-2.6.32-32.62: 
git checkout -b bisect Ubuntu-2.6.32-32.62 

Build from the schroot (follow article above): 
sudo schroot -clucid-i386 

Start bisection: 
$ git bisect start Ubuntu-2.6.32-32.62 Ubuntu-2.6.32-31.61 
Bisecting: 89 revisions left to test after this (roughly 7 steps) 
[1198ae36cd30092718563b42e2f1d847516a5e45] fbcon: Bugfix soft cursor detection 
in Tile Blitting 

Update the debian.master/changelog with an entry for the custom kernel test 
package e.g.:
linux (2.6.32-32.63~tellis01LP805209) lucid; urgency=low

Prepare for the build (this creates the needed files in the debian/ directory 
from the debian.master copies): 
fakeroot debian/rules clean 

Build it: 
$ skipabi=true skipmodule=true fakeroot debian/rules binary-generic-pae
