The timestamp resolution is cool, the fractional part isn’t all zeroes anymore (see a file not yet touched and a file touched with touch after my upgrade):

And:

Saturday, 2008-Oct-25 at 05:45:12 - mbt@zest - Linux v2.6.28
Ubuntu Intrepid:[1-25/9412-0]:~> mount | grep home
/dev/sda6 on /home type ext4 (rw,relatime)
gvfs-fuse-daemon on /home/mbt/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=mbt)

Works for me. Will play more with it tomorrow.

And no, I didn’t package it (the kernel) up… to build it, just follow the instructions that come with the kernel, and then on Ubuntu, run update-initramfs and update-grub. If you use the NVIDIA driver 177.80, see my previous post for a change that needs to be made to /var/lib/dkms/nvidia/177.80/source/nvacpi.c and the kernel tree to make it build on the next reboot after upgrading your kernel.
