IBM 486DX2-50, Cirrus Logic

Is halloween. Yesterday I work till late night, try to get XFree86-4.4 (with freetype support) working on the machine, but fail. Luckily the old version(v3.x) is still working. The machine have a on board GD5430 display chipset (by Cirrus Logic), 1M memory, but I just need a 640x480 256 colors to match with my grey scale IBM monitor. XFree86 team doesn't do a good job here, the new driver don't support the old Cirrus Logic GD5430 Chipset. I suppose to use FrameBuffer. The frame buffer driver is with linux kernel, but the new linux kernel don't support the old driver too. Too bad.
