Its never worked for me, but I haven't done anything on it since the new kernel
came out. But anyway, so all you did was patch the kernel with a custom DSDT?
Are there any instructions on how to go about doing this, anywhere?

Many thanks!

This link should have pretty much all the information you need:

It was written in January 2004 so a few things have change since then,
you don't need to apply a patch to the kernel anymore, there's an option
for a custom DSDT in the kernel already. But if you use the FC3 config
files you'll need  to disable "Select only drivers that don't need
compile-time external firmware" in the Device Drivers/Generic Driver
before you can enable it.

So actually I *do* need to recompile my kernel (given that I only use
the stock kernels from Fedora Core and Fedora Core Updates Released) to
use a custom DSDT? I'm not sure if I understood you correctly. You're
saying that it is now possible to use a custom DSDT without compiling it
into the kernel, but the stock FC kernels have not been compiled in such
a way to take advantage of this. In which case, has anyone opened a bug
report asking that they enable this option?

Best, Darren

Yes you do need to recompile the kernel but you don't need to apply the
patch for using a custom DSDT since it's already in the newer kernel.
(Not sure when it was applied though) but you do need to recompile the
kernel to tell it to use your custom DSDT file. You can't compile the
kernel with this option if your doing a generic kernel for different
computers because the custom DSDT will be compiled in the kernel so
that's why you have to compile it with your DSDT for your computer.

I hope that's a bit clearer now!
