Check out the virtual-dev package (in experimental).

Description: Limits disk spin-ups by putting /dev/ on a ramdisk
This package attempts to reduce unnecessary access to your IDE disk by
creating a ramdisk at boot time, copying the /dev/ directory onto it,
and mounting the copy over the top of the real /dev/ directory.
Normally, accesses to devices in /dev/ will cause the kernel to write
an updated last-access time to the disk. This ramdisk scheme will cause
those writes to go to the ramdisk, and thus not spin up your hard disk.
This package is still experimental; install it only if you can fix
