R03L: If you're using Slackware, you will need to use the source tarballs. If your Slackware install has RPM support, you can also use the SRPMs. Please note that you will have to have a kernel source tree installed that's configured to exactly match your running kernel. Older versions of Slackware shipped an unconfigured kernel source tree, so you might need to rebuild your kernel.
Please see the README for more details.
You should use the IA32 driver (1.0-4191), *NOT* the AMD64 driver.
