Yeah, that's how I started my own configs for 2.6.34, then I always
use make localmodconfig to trim crap down. In this case my config just
stopped working on newer kernels. What cured it was I took Daniel J
Blueman's 2.6.35 ubuntu package:
http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-2.6.35-9-generic_2.6.35-9.14_amd64.deb
Then stole that config and used it as a starting reference, then did
the localmodconfig after booting into it and cp'ing that config to my
own and running oldconfig.

Right, I thought it was the rootfs, the rootfs is provided through the
tmpfs filesystem which both configs have. They also have devftmpfs.
This is why I started to suspect something on the distribution side
but low and behold linux-image-2.6.35-9-generic_2.6.35-9.14_amd64.deb
worked well.
CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y
CONFIG_TMPFS=y
CONFIG_TMPFS_POSIX_ACL=y
Good news is its working now but certainly my old config did not work anymore.
