In /etc/conf.d/net, the ifconfig line: routes_eth0=( "default via 192.168.1.12" ) result in: route add default gw -net 192.168.1.12 metric 0 dev eth0 (or something close to that). As a result, networking is pretty much hosed. 192.168.1.12, here, does NAT for everyone in the company. I changed /lib/rcscripts/net.modules.d/ifconfig line 306 to: [[ " ${x} " != *" -net "* && " ${x} " != *" -host "* && " ${x} " != *" default "* ]] && x="-net ${x}" so I could at least boot the computer. (Although, not being able to boot may have been from vmware, not this. I also remove vmware from the boot process, because it always hung and I didn't want to find out why.)
How exactly is it "hosed"? After trying your patch, the routing table is exactly the same as it was before your patch for default routes. If you dis-agree then please re-open this bug, post any error messages relating to adding the default route, the routing table you end up with and the routing table you exepct.
