*/
/*
* Changes:
*
* 23/08/2001 Abraham van der Merwe <abraham@2d3d.co.za>
* - Fixed display timing bug (mode information for some
* modes were not initialized correctly)
* - Added workarounds for GTT corruptions (I don't adjust
* the pitches for 1280x and 1600x modes so we don't
* need extra memory)
* - The code will now default to 60Hz if LFP is connected
* - Added different refresh rate setting code to work
* around 0x4f02 BIOS bug
* - BIOS workaround for some mode sets (I use legacy BIOS
* calls for setting those)
* - Removed 0x4f04, 0x01 (save state) BIOS call which causes
* LFP to malfunction (do some house keeping and restore
* modes ourselves instead - not perfect, but at least the
* LFP is working now)
* - Several other smaller bug fixes
*
* 06/09/2001 Abraham van der Merwe <abraham@2d3d.co.za>
* - Preliminary local memory support (works without agpgart)
* - DGA fixes (the code were still using i810 mode sets, etc.)
* - agpgart fixes
*
* 18/09/2001
* - Proper local memory support (should work correctly now
* with/without agpgart module)
* - more agpgart fixes
* - got rid of incorrect GTT adjustments
*
* 09/10/2001
* - Changed the DPRINTF() variadic macro to an ANSI C compatible
* version
*
* 10/10/2001
* - Fixed DPRINTF_stub(). I forgot the __...__ macros in there
* instead of the function arguments :P
* - Added a workaround for the 1600x1200 bug (Text mode corrupts
* when you exit from any 1600x1200 mode and 1280x1024@85Hz. I
* suspect this is a BIOS bug (hence the 1280x1024@85Hz case)).
* For now I'm switching to 800x600@60Hz then to 80x25 text mode
* and then restoring the registers - very ugly indeed.
*
* 15/10/2001
* - Improved 1600x1200 mode set workaround. The previous workaround
* was causing mode set problems later on.
*
* 18/10/2001
* - Fixed a bug in I830BIOSLeaveVT() which caused a bug when you
* switched VT's
*/
/*
* 07/2002 David Dawes
* - Add Intel(R) 855GM/852GM support.
*/
/*
* 07/2002 David Dawes
* - Cleanup code formatting.

* memory.
* - Fix screen blanking.
* - Clear the screen at startup so you don't see the previous session.
* - Fix some HW cursor glitches, and turn HW cursor off at VT switch
* and exit.
