i tried this one with success
i too had some problems getting my onboard ethernet running.
after installing the newest drivers, the ethernet card was detected, but still no response from the dhcp server.
in the end, i had to deactivate the acpi feature.
the bootloader i use is "grub" on a SuSE 8.2 system. there i only had to add the lines noacpi in the options section of the system which i want to boot.
after that, everything worked fine.
