To the contrary! If you do not use an initrd or initramfs, the kernel
itself will trigger resume on boot (provided there is a suspended image)
before any scripts are run, so no disk will be mounted, no data destroyed.

So the point is, if you use an initrd or initramfs, do not touch any
disk/partition that was mounted R/W in the suspended instance of the
system.
For partitions mounted Read-only your mileage may vary (I am guessing
here). Mounting such a thing read-only should be ok, rw could get you
intro trouble because the disk may change without the suspended system
knowing it...

Hope this helps.
