With both the recent old and the current libata your pcmcia or cardbus subsystem as appropriate should discover the device. ide=a,b,c won't actually work because the kernel pcmica subsystem will re-init the port from the BIOS whacky setup to normal PCMCIA/Cardbus. Not tried this on the Z600 but it is true for several others. If it doesn't work on the Z600 get more some dmi strings, lspci dumps and verify what the pcmcia layer does and we can make it automatic as it should be.
