Comment 76 for bug 994685

This is a proposed change for the kernel, which workarounds this issue. It adds a new fixup (quirk) for this machine. Seems to do what is intended checking under hda-emu. On Monday I'll build and provide some testing packages, just attaching the patch here first for any desired review or if anyone wants to build early.

The patch should only should affect the Dell machine here and has also some sanity checks, so should be safe for an SRU.
