I have a Matrox G400 Dual Head Max that I was hoping to use with direct 
rendering.  The kernel identifies it just fine:

agp0 at pchb0 (v2): aperture at 0xd0000000, size 0x10000000
vga0 at pci1 dev 0 function 0: Matrox MGA G400 AGP (rev. 0x04)
mgadrm0 at vga0: Matrox G400/G450 (AGP) (unit 0)
mgadrm0: AGP at 0xd0000000 64MB
mgadrm0: Initialized mga 3.2.2 20060319

but then, later on, says

WARNING: module error: builtin module `drm' failed to init

When using modular xorg and xf86-video-mga, upon starting X the kernel says:

error: [drm:pid13731:drm_addmap] *ERROR* offset/size not page aligned: 
error: [drm:pid13731:mga_do_agp_dma_bootstrap] *ERROR* Unable to map WARP 
microcode: 22
error: [drm:pid13731:drm_addmap] *ERROR* offset/size not page aligned: 
error: [drm:pid13731:mga_do_pci_dma_bootstrap] *ERROR* Unable to create mapping 
for WARP microcode: 22
Try to use drm in xorg with a Matrox card.  I don't know if this affects other 
drm drivers as this is the only drm-capable card I have.
none, sorry.
