The device mapper runs in the kernel, but it has no knowledge of the lvm structures. This is all done at user level. I've forgotten in the thread whether or not this is a removable device. If it is, you can plug it in after startup, hdparm if that makes you more comfortable, and then rescan for physical volumes. If it is a more permanently attached volume, you might have to modify the OS's startup scripts to achieve this. Perhaps you should use a CD-bootable rescue system (I recommend RIP Linux). At least RIP boots up, and you have to start LVM manually, which would give you a chance run hdparm and make it read only.
