Hello,
I've installed Redhat 8.0 on a Compaq TC1000 tablet computer that I own. 
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.

Thanks,
Frank
