[PATCH 0/2] [Jaunty] LP#349314 -- MCHBAR enable

[Andy Whitcroft]

Some machines including the Eee 901 do not enable tiling due as the
BIOS does not allocate the MCHBAR registers correctly.  The following
patches reserve this space when the BIOS has failed to do so and enabled
the support.  This has been tested and confirmed to majorly improve
performance on these systems.  This set has also been confirmed not to
cause regressions with those Thinkpads which appeared to be affected by
the previous patches.

Proposing for SRU to Jaunty.
