xfree86: Use fbdev/vesa driver on Oaktrail, Medfield, CDV rather than -intel
Instead of defaulting to -intel for Oaktrail, Medfield, and CDV chips,
default to -fbdev. For Poulsbo (only), attempt to use -psb if it's
installed, and fallback to fbdev otherwise. All other Intel chips
should use -intel.
This fixed an issue where -intel would load on these chips and cause a
boot failure. Newer -intel drivers avoid the boot hang, but it's still
the wrong driver to load, so why take chances.
The patch was originally created by Stefan Dirsch for OpenSUSE. We have
included it in our stable release (Ubuntu "quantal" 12.10) since
December.
