[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. Signed-off-by: Thomas Winischhofer <thomas@winischhofer.net> Cc: "Antonino A.
