[PATCH] sisfb update

This lifts sisfb from version 1.7.17 to version 1.8.9. Changes include:

- Added support for XGI V3XT, V5, V8, Z7 chipsets, including POSTing of
  all of these chipsets.

- Added support for latest SiS chipsets (761).

- Added support for SiS76x memory "hybrid" mode.

- Added support for new LCD resolutions (eg 1280x854, 856x480).

- Fixed support for 320x240 STN panels (for embedded devices).

- Fixed many HDTV modes (525p, 750p, 1080i).

- Fixed PCI config register reading/writing to use proper kernel
  functions for this purpose.

- Fixed PCI ROM handling to use the kernel's proper functions.

- Removed lots of "typedef"s.

- Removed lots of code which was for X.org/XFree86 only.

- Fixed coding style in many places.

- Removed lots of 2.4 cruft.

- Reduced stack size by unifying two previously separate structs into
  one.

- Added new hooks for memory allocation (for DRM).  Now the driver can
  truly handle multiple cards, including memory management.

- Fixed numerous minor bugs.
