I was talking about these:
# ls /usr/lib64/xorg/modules/drivers
ast_drv.so       ch7xxx.so         i810_drv.so   r128_drv.so
savage_drv.so         tfp410.so       voodoo_drv.so
ati_drv.so       cirrus_alpine.so  intel_drv.so  r500_drv.so
sil164.so             trident_drv.so
atimisc_drv.so   cirrus_drv.so     ivch.so       radeon_drv.so
siliconmotion_drv.so  vesa_drv.so
ati_r500_drv.so  cirrus_laguna.so  mga_drv.so    radeon_tp_drv.so
sis_drv.so            vga_drv.so
ati_tp_drv.so    dummy_drv.so      nv_drv.so     s3_drv.so
sisusb_drv.so         via_drv.so
ch7017.so        fbdev_drv.so      qxl_drv.so    s3virge_drv.so
tdfx_drv.so           vmware_drv.so

Running Centos. I suppose all these above are for handling different video
cards ?
