Chameleon 2.0 has recently been updated to RC3.

"This RC3 build is a small update to RC2, but we’re providing the long-awaited proper Snow Leopard extensions loading and a few fixes like 1TB+ disk addressing support. There are also some changes have been made to the graphics enabler and to the smbios patcher. Also you can even build the Chameleon sources under 10.6."

New options:

• SMBIOS
  Finally you can specify your smbios.plist location using a device selector prefix like “SMBIOS=rd(0,0)/Extra/smbios.plist”.
• VideoROM
  You can pass an alternate video ROM image file to the system.
• VBIOS
  Using this boolean switch, you can control the injection of your video BIOS to device-properties. We got various reports if this switch is really needed to make your graphics device handled correctly by the system.
• Version specific kexts
  You can use the same booter partition for both Leopard and the recent Snow Leopard; to do that you can put your OS version specific KEXTs/MKEXT this way:
  Code:

  /Extra/10.(5|6)/Extensions[.mkext]
