 1.3  20-Feb-2011  jakllsch Follow a minor detail in the spec a bit more closely.
 1.2  09-Feb-2011  jmcneill Add VESA VBE/DDC EDID support for determining the monitor's preferred
video mode. "vesa on" will now select the preferred mode @ 8bpp if it can
be determined and is supported by the display adapter, otherwise it will
use 640x480 @ 8bpp.
 1.1  16-Feb-2009  jmcneill branches: 1.1.2; 1.1.4; 1.1.6; 1.1.10; 1.1.12; 1.1.14;
Bootloader modifications for generic framebuffer console support on i386
and amd64 where VESA VBE 2.0+ is available.

* Add helper library and stubs to invoke VBE bioscalls.
* Bump HEAP_START as we were already dangerously close to our limits.
* bootdataseg now allows access > 16MB so in the future we can scribble
on the framebuffer.
* Pass BTINFO_FRAMEBUFFER parameters to kernel when configured.
* VBE modes are configured with the new 'vesa' command. Usage, when present:
* vesa {enabled|disabled}
Enable / disable linear framebuffer, default mode is 640x480x8. May
be changed in the future to determine mode based on VBE/DDC where
available.
* vesa list
List modes supported by the firmware that meet the following criteria:
* linear framebuffer
* packed pixel or direct colour mode
* vesa {modenum|modestr}
Enable specific VBE mode. The mode can be specified either as a
VBE mode number (eg. 0x101) or as a string (eg. 800x600x16).

 1.1.6.4  28-Mar-2011  jym Sync with HEAD. TODO before merge:
- shortcut for suspend code in sysmon, when powerd(8) is not running.
Borrow ``xs_watch'' thread context?
- bug hunting in xbd + xennet resume. Rings are currently thrashed upon
resume, so current implementation force flush them on suspend. It's not
really needed.
