At some point since 2.6.22, the aha152x_cs driver stopped working and started erring on load with the following messages: kernel: pcmcia: request for exclusive IRQ could not be fulfilled. kernel: pcmcia: the driver needs updating to supported shared IRQ lines. With the following change, the driver works with shared IRQs.
