From the web messages cardbus does not work as no IRQ can be mapped. This is a physical problem because the wires for INTx is not connected. Linux will report IRQ 0 and tell you to use biosirq but it does not help. Only non-cardbus devices work. It is nice if someone can tell us how to fix it?
The Cardbus of the 760ED is working fine if you patch the kernel to route IRQ to a isa interupt.
