David, this is the kernel that comes with Slackware v4.0. I have noticed that Slackware v7.0 is now available (skipping 5.0 and 6.0).
I intend to upgrade the PCMCIA support version from 3.0.9 to 3.1.x (as sugggested by Nathan). IF that doesn't work, then I will get Slackware v7.0, which uses kernel 2.2.13.
To the best of my knowledge, it appears to be a IO Port or MemoryAddress or even IRQ problem. I have tried various settings, and have basically received the same error.
