include M1541, M1621, M1631, M1632, M1641,M1647,and M1651.
For the ALi-chipset question, ALi suggests you refer to

You should say Y here if you use XFree86 3.3.6 or 4.x and want to
use GLX or DRI, or if you have any Intel integrated graphics
chipsets. If unsure, say Y.
The M1541 chipset can do AGP 1x and 2x, but note that there is an
acknowledged incompatibility with Matrox G200 cards. Due to
timing issues, this chipset cannot do AGP 2x with the G200.
This is a hardware limitation. AGP 1x seems to be fine, though.
