Fedora Core 4

I am having problems getting my HSF Softmodem driver installed properly on Fedora Core 4.

I used the cnxtinstall script, and it did show the downloaded drivers being compatible with my running kernel, but it generated errors while trying to compile the drivers after it downloaded them. 

There was some mention of obtaining a custom Fedora Core 4 kernel with 16k stacks, but I could not find anything on your site to download (although I don't think this was the problem with the compile). 

If anyone can help, it would be appreciated. Thanks.
