Dump e1000 registers on detection of PCI error.
This patch asks that the arch re-enable MMIO long
enough to perform the register dump -- and then
it requests the usual card reset. Works good for me.

This patch requires the patch at
http://sourceforge.net/tracker/index.php?func=detail&aid=1460945&group_id=42302&atid=447451

(patch "1460945 tx hang debug code" from Jesse)

to be applied first. This patch also requires some
recent PowerPC patches to be applied: google for
[PATCH 0/4]: PowerPC: EEH: Add support for MMIO enabled
