- Calculate host-to-screen data size for "source stride packing" in color mode
  similar to the monochrome mode.
- Set up data swizzle mode for all launch area operations.
- Temporarily draw polygon in normal mode in case the currently unsupported
  pattern mode is selected.

69c4758fbb New attempt to fix the Banshee bitblt issues in host-to-screen mode with
monochrome source and "source stride" packing. Now adding the source stride
converted to pixels to the 5-bit srcX value.
TODO #1: color source needs to be handled in a similar way (no test case yet).
TODO #2: clipping needs to be rewritten at least for host-to-screen blts.

caf52aacac Added advanced PCI option 'noagp' for the i440BX chipset.
Since AGP support is incomplete, it may be useful to disable this subsystem.

e1265b7536 Fixed special rule for the backward compatible device type selection of card #0.
If at least one ne2k device is assigned to a PCI slot, card #0 defaults to PCI
type, unless type is set up in ne2k line.

ad3090ab1a Some small fixes found with original Cirrus VGABIOS at VBE mode testing.
- Setting up bank #0 modifies the external offset for VRAM access in VGA core.

733e466628 Split the VBE bank into separate read and write apertures. The compatibility
mode sets both banks to the same value. Reading VBE bank register always
returns the write aperture setting. This feature is designed for the scrolling
function of the VBE 'write character' support. VBE code should use compatibility
mode for now.
TODO: update VGABIOS to use this feature.

8cbf4eff8e Some changes for the Bochs VBE 32k bank granularity feature.
- VBE enable register returns 32k granularity flag if enabled.
- VBE bank register returns 32k granularity flag if VBE_DISPI_GETCAPS is set.
- Defining new DISPI ID not necessary.
- TODO: update VGABIOS to use this feature.

43033b2137 Some changes for the Bochs VBE support.
- Limit VBE bank size to 64k as expected.
- Enabling VBE mode now clears the whole video memory for all bpp modes unless
  "noclear" bit is set.
- Prepared 32k bank granularity mode required for text output functions. Added
  new VBE_DISPI_ID6 to indicate this capability. The default is still 64k.

Since this save/restore list exists in all devices, it's safe to move the new
code to the usb_device_c destructor.
