Get the Via EPIA-N(L)/CN400 to a reasonable level of maturity::
Tested on Via EPIA-NL8000EG with FILO payload booting FC9 (2.6.25 kernel) from SATA HDD. ACPI is working for PCI interrupt routing, some memory stuff and Soft-Off. USB/SATA Working VGA Console Working X Working via Onboard AGP Removed dsdt.c, fixed some whitespace.
