Same here, with OpenGL working fine:

wonko@weird ~ $ fglrxinfo 
IRQ's not enabled, falling back to busy waits: 2 0
display: :0.0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: Mesa DRI R600 (RS780 9610) 20090101  TCL
OpenGL version string: 2.0 Mesa 7.8.2

For more information, use glxinfo, not fglrxinfo, which is from the ati-
drivers package:

wonko@weird ~ $ glxinfo 
name of display: :0.0
IRQ's not enabled, falling back to busy waits: 2 0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
[...]

But it seems you direct rendering is disabled. Is the drm module loaded? 
That is, does 'lsmod | grep drm' show it? If not, try loading it with the 
modprobe command before starting X, and see if there's a difference (diff 
/var/log/Xort.0.log*).
You yould also try the closed-source ati-drivers. Exchange the 'radeon' by 
'fglrx' in the Device->Driver line for this, and run 'eselect opengl set 
ati'. Also make sure the fglrx kernel module is loaded, and the drm module 
is unloaded (and vice versa). You need to havwe 'fglrx' in your 
VIDEO_CARDS variable in make.conf (and 'radeon' for the open source 
driver).

I had blank screens, too, but it was only the mouse missing, which I only 
saw when I started a window manager, not only X itself.
