Mirror what is done for amd64 boot and ACPI wakeup code by setting CR0_WP (write protection bit) early on boot. Although it is set later via cpu_init(), this can help tracking down invalid writes to pages mapped as read only from ring 0. No regression observed when booting under anita (QEMU) or a P4 host. Depending on your hardware or setup, you may trigger code paths I have overlooked. So if your machine does not start properly, or you get page faults early during boot, please report them to me.
