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.

7ba54c951d LGPL'd VGABIOS updated from SVN. 
- Banshee: added 'write character' support for 8 bpp modes.
- Banshee / Cirrus: report TTY support for 8 bpp VBE modes.
- FIXME: Banshee scroll code works for 'scroll up' only.

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.

049826aa32 Fixed possible segfault in case of invalid filename based on patch #559. 
Since this save/restore list exists in all devices, it's safe to move the new
code to the usb_device_c destructor.

faa11624e0 Updated LGPL'd VGABIOS from SVN. 
- Added initial version of the VGABIOS for Voodoo Banshee adapters.
- Several code optimizations to reduce binary size.
NOTE #1: Banshee version has no VBE support yet.
NOTE #2: Banshee binary uses PCI ID for Banshee PCI and Bochs temporarily
         modifies the PCI data for Voodoo3 and AGP models.

Volker Ruppert
69695bfd67 Prepared the Banshee code for the planned LGPL'd VGABIOS with 3dfx Voodoo

857c3be2ba Some work on the Voodoo Banshee code. 
- Moved setup of default i/o register values to reset().

- Don't overwrite readonly bits in miscInit1 register.
- Set up subsystem ID in VGABIOS ROM in case it's > 32k (doesn't exist yet).
- Copy subsystem ID from ROM to PCI config registers in reset().
