You can add to this section, e.g.:
Section "Device"
Identifier "Configured Video Device"
Driver "radeonhd"
Option "AccelMethod" "default"
EndSection
You can try other options mentioned in "man radeonhd"; you can also
go back to the "radeon" driver and experiment options from its manpage.
It would also be interesting if switching to the "vesa" driver restores
VT switching.
The radeonhd driver seems to support RandR; you can experiment with that
according to "man xrandr".
