All you should have to do is change your rc.inet1.conf DHCP info and then restart rc.inet1
On my laptop, eth0 is my ethernet card and eth1 is my wireless card. So, if I want to switch from wireless to LAN, I remove the "yes" from "USE_DHCP[1]" and add a "yes" to USE_DHCP[0]
Then /etc/rc.d/rc.inet1 restart
Vice-versa if you want to go from LAN to wireless. I've made a /sbin/network script that does everything for me. I have several wireless hotspots that I connect to and I got tired of modifying my rc.wireless.conf and rc.inet1.conf...
In case you are even remotely interested, I'll post it. It's extremely amaturish and overly long but it get's the job done. This is on my own SysVinit Slackware version so locations/names of the files are different than where Slackware puts them. But that's easy enough to change to suit Slackware.

Isn't that the most absurdly sloppy thing you've ever seen?
Hey... It works...
This is on a Powerbook so my airport card is supported under the kernel. rc.inet1.conf has support for wireless devices assigned as wlan0 if it happens to have that designation under ifconfig/iwconfig..
You can also call rc.inet1 with specific device arguements...
/etc/rc.d/rc.inet1 eth0_start
