This might be another symptom of the same problem.

That suggests to me that some problem with recognizing the monitor as
connected during the VT switch might be responsible for your issue. (I
have no experience with Radeon HD chipsets, so I am really only guessing
here.)

But still no luck with switching to the console, I assume?

Not really, you just loaded another module that could provide a driver
for a framebuffer device. (This is different from the Xorg driver module
for your card.)
It would be interesting to know if you get a /dev/fb? device once
radeonfb is loaded. (I am not too optimistic, though.)

You can just edit your /etc/X11/xorg.conf, replace "radeon" or "ati"
with "radeonhd" and restart X. (The package xserver-xorg-video-radeonhd
has to be installed.)
Mind you, I do not know how stable the current version of radeonhd is;
it is still a relatively new driver.
