What kernel drivers are you using?

Here's my fstab on my x64 box that has been booting perfectly for
months. And I boot it lots because it's my dev't box:

LABEL=boot     /boot         ext3          noauto,noatime  1 2
LABEL=root     /             ext3          relatime        0 1
LABEL=swap     none          swap          sw              0 0
LABEL=usr      /usr          ext3          relatime        0 2
LABEL=var      /var          ext3          relatime        0 2
LABEL=opt      /opt          ext3          relatime        0 2
LABEL=home     /home         ext3          relatime        0 2
