O Xorg.N.log (onde N é o número do DISPLAY) deve dizer. Para ter o log
é só mover o xorg.conf para outro lugar e executar um xinit -- :N
(denovo, N é o número do DISPLAY), uma vez iniciado, tu vai ver que
ele vai tentar detectar automaticamente a placa, mais ou menos assim:

No meu caso ele tenta o nv, depois vesa e depois o fbdev, como tu pode ver aqui:
(II) LoadModule: "nv"
(WW) Warning, couldn't open module nv
(II) UnloadModule: "nv"
(EE) Failed to load module "nv" (module does not exist, 0)
(II) LoadModule: "vesa"
(WW) Warning, couldn't open module vesa
(II) UnloadModule: "vesa"
(EE) Failed to load module "vesa" (module does not exist, 0)
(II) LoadModule: "fbdev"
(WW) Warning, couldn't open module fbdev
(II) UnloadModule: "fbdev"
(EE) Failed to load module "fbdev" (module does not exist, 0)
(EE) No drivers available.
OBS: Como eu não tenho os pacotes (xf86-video-nv, xf86-video-vesa e
xf86-video-fbdev) destes drivers instalados, os erros são "normais".
Agora se por driver tu quis dizer "módulo do kernel" o lspci mostra
sim, tu tem que usar a opção -v, olha ai (nas duas linhas no fim):
