Bug Description
I have two video cards installed:
# lspci | grep VGA
01:00.0 VGA compatible controller: nVidia Corporation NV34 [GeForce FX 5200] (rev a1)
02:02.0 VGA compatible controller: ATI Technologies Inc 3D Rage II+ 215GTB [Mach64 GTB] (rev 9a)
#
Eventually, I want to use Xinerama across the two cards, but for now I want to use the Mach64 as a single X-Server.
If I take out the NVidia card, everything works perfectly (out of the Mach64 card). If I put the NVidia card back, then startx fails and following error is reported (in Xorg.0.log):
(**) MACH64(0): Depth 24, (--) framebuffer bpp 32
(==) MACH64(0): Using XAA acceleration architecture
(WW) MACH64: Mach64 in slot 2:2:0 could not be detected!
(II) UnloadModule: "mach64"
(EE) Screen(s) found, but none have a usable configuration.
Fatal server error:
no screens found
I suspect some IRQ, ports or memory ranges conflict, but unfortunately I am not capable to diagnose it further. If this is the case, the error message above must be more informative.

Currently it is not possible to use other drivers together with NVIDIA's proprietary driver. You can try uninstalling the "nvidia" driver and setting the driver back to "nv" (you will lose 3D acceleration though).
