Only Intel GMA 900 (the same chipset in the Apple Develeoper Kit) can support full 2D/3D Graphics Aceel.
Other chipset like ATI Radeon / NVIDIA Geforce has driver support. The other chipset can only support by VESA VGA Driver(you can only use 1024x768 at 32bpp)
but I faced a problem that all Chinese Input Method cannot be used under Tiger X86. Even OpenVanilla v0.7.1 cannot use. It might be IME is a special program that cannot run under Rosetta.
