I upgraded the kernel to 2.4.20+ the corresponding ACPI patch from sourceforge. I have compiled the kernel with CONFIG_ACPI_DEBUG. The TC1000 is fairly standard except for two devices. The first being the touchscreen and the second some related buttons. I finally tracked down the devices under windows and found that both are configured via ACPI. I've attached the corresponding snippet from dsdt. The first device is nothing more than a serial port on com1 (I believe). The corresponding windows driver is a serial driver. The other one I am not sure about. My question is: how can i get these devices initialized via ACPI? If someone could point me in the right direction, I'd greatly appreciate it.
