Thanks, Jean-Phillipe; that worked. (Nate, I didn't try your suggestion, but thanks anyway :)
For other's future reference, here's what I did (everything as root, so there's probably a better way...) 1) Install the device3dfx-source package (apt-get install device3dfx-source) and the kernel-headers-X.Y.ZZ package, where X.Y.ZZ is your kernel version (e.g. 2.2.17). 2) If you don't have the kernel-source-X.Y.ZZ package installed, do this: mkdir /usr/src/linux ln -s /usr/src/kernel-headers-X.Y.ZZ/include /usr/src/linux/include (If the directory /usr/src/linux already exists, I think the easiest thing to do is 3) cd /usr/src/modules/device3dfx/ ./debian/buildpkg This creates a device3dfx-module-<something>.deb in /usr/src; install it using dpkg -i device3dfx-module-<something>.deb Installing the package will create a device /dev/3dfx ; its permissions are 660, which means normal users can't use apps that want to access the device. 'chmod o+rw /dev/3dfx' will change this, though I'm not sure how advisable it is. Aaron
