This XF86Config file, created by Keith Goldman with help from Przemek Klosowki, works under XFree86 3.3.2 by using the cyber9397 driver. The problem disapeared with only the LCD enabled. Download L4102.009 from here and see these instructions for how to install the update. I'd suggest trying out both XFree86 and the XiG demo and decide for yourself. The only IRQs that seem to work for me are 3 and 11.
Some drives claim to support multiple mode, but lose data at some settings.
I found that the CD reader is not recognized unless the machine is booted with it in the VersaBay. This involves recompiling the kernel after changing a few parameters to activate full APM bios support, and downloading and installing some version of the apmd utilities.
