You're absolutely right that ext{2,3,4} partitions need to be
read-only for fsck. The latter throws up a very scary warning if you
try to run it on a partition mounted read-write. Here's the kernel
line from /boot/grub/menu.lst (haven't converted to grub2 yet):
kernel /vmlinuz-linux
root=/dev/disk/by-uuid/a7f84383-2cc2-4d70-adb5-3bf909a3f99b loglevel=3
ro quiet splash
resume=/dev/disk/by-uuid/2d185a12-115f-4f93-99a3-bfca4d0fc216
init=/bin/systemd
