item entry. * The bios_ia32 video platform code now stores the available VESA modes in the new vesa_modes kernel_args field. * When configuring a VESA mode via settings file, it's no longer needed to specify the exact mode - the closest available mode is now used. This should help with bug #1962. * frame_buffer_console_init() now also creates a boot_item for the VESA modes in the kernel_args. * The VESA accelerant now filters the mode list to only contain modes that are actually supported. * Moved non-shared vesa driver data into its own file vesa_private.h. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24675 a95241bf-73f2-0310-859d-f6bbb57e9c96
