	I, too, have had difficulty on older Gentoo systems with a 2.4.x  
kernel.

	the latest release of 3DM2 (9.3.0.4) seems to have corrected a lot  
of issues when run with 7-8xxx controllers. I have a few systems with  
8006-2 controllers and one with a 7506-4 that have 3DM2 running  
happily. but all those are running 2.6.x kernels... so I'm not sure  
if there are still issues with 3DM2 on 2.4.x kernels.

cheers,
