As far as I know, much of the names for stuff like filesystems were changed with 2.6.x, so you'll have to check out the new terminology somewhere.
You can also use the tool "mkinitrd" to convert your old fstab to the new one. If you have that tool installed, use:
generate-modprobe.conf | tee /etc/modprobe.conf
Then restart. Works under SuSE9.0, dunno about other distros.
