I added a link in "rc3.d" as:
S98network --> ../init.d/network

The interfaces now start at boot up (thanks!), but the default route 
(via the gateway) is not found, even after editing the "ifcfg-ethx" 
files as Michael Corral suggested. All other parameters get set 
properly. Perhaps I should start the network earlier, with a lower 
sequence number?

To set the default route, I need to state, manually:
route add -net 0.0.0.0 netmask 0.0.0.0 gw 192.168.3.254 dev eth0

Somehow, this default route is not found by a network restart in 
spite of the gateway address being specified (and bound to eth0) in 
various files.

FWIW, the Fedora-10 GUI configuration utility is totally useless: it 
corrupts the interface configuration files beyond functionality.

With regards to "ifcfg-ethx", I find copies in these three directories:
/etc/sysconfig/networking/devices
/etc/sysconfig/networking/profiles/default
/etc/sysconfig/network-scripts

Which one has precedence? They seem to synch each other, but only 
more-or-less: it takes multiple boots before they are all sync'd. It 
seems awfully messy to have multiple files meant for the same purpose...

One further annoying problem that I have is that my gateway locks up 
when my Fedora-10 server boots. That gateway keeps working properly 
if I disconnect the Ethernet wire to the F-10 server while it boots. 
It is as if the booting system sniffs around in IPv6 mode before 
settling into IPv4. Is it a good idea to disable IPv6 entirely in 
this day and age? I'll return the favor of any answer by asking how 
to enable and configure IPv6 after I have installed Fedora-13 :-)
