Trouble with getting 3 pointing devices working under X

[underpaid]

I'm using an Inspiron 8100 with RH 7.3, and having trouble getting the trackpoint, trackpad, and a usb ms intellimouse to work under X at the same time. If anyone knows any good resources for getting that configuration to work, or knows how to get it working, or maybe just the trackpad and the intellimouse working, please reply. Thanks.
