FC1, ACPI, and Compaq Evo N800c

[Mike Wohlgemuth <mjw@xxxxxxxxxx>]

I've got a Compaq Evo N800c on which I am currently running RH9 with a 
custom patched and compiled 2.4.20-18 kernel.  It took me about 2 weeks 
of reading up on ACPI and tracking down a custom DSDT and patches to get 
it working.  I'd like to try Yarrow on it, but I'm cringing at the 
prospect of having to figure everything out on a new kernel version.  Is 
anyone running Yarrow on an Evo N800c, or similar machine?  Care to 
share how you configured it?  Barring that, would everything work 
reasonably well if I upgraded to Yarrow but continued to use the old kernel?

Thanks
Mike
