Possible workaround for bad timestamp on modules.dep

[John Dalbec <jdalbec@cboss.com>]

I got a good timestamp on modules.dep by renaming
/etc/rcS.d/S50hwclock.sh to /etc/rcS.d/S20hwclock.sh.
Is this safe?  I rebooted and nothing appears broken yet.
(I have my Hardware Clock on local time (EST) to satisfy another OS.)
