If it is any help, I am using a similar Dell E6400 with the latest Fedora 10.
My sound works fine, but my 3D graphics aren't accelerated (using the open source nv Xorg drivers), Bluetooth doesn't seem to work and the Broadcom BCM4322 drivers came from the rpmfusion repository. Like you - my suspend/resume doesn't work at all. -- This message posted from opensolaris.org
