Did a few tests more:

1) Section "ServerLayout"
    Option "AllowEmptyInput" "false"
Section "Device"
       Driver      "radeon"
moused running
hald running

Result: X (gnome in my case) starts, mouse moves. Upon leaving X the
console is to something different than 80x25 lines - at least I can't
see about 2-3 lines on the bottom of the screen. However - as soon as
a start X again I get graphical junk on the display, mouse & keyboard
frozen, no switching of consoles nor can I log in via the net (ssh)

2) Same as 1) above however this time with
Driver "radeonhd"

Result: Almost the same as 1) above - only difference: When I leave X
the console comes back again to 80x25 lines. Hoever - like in 1) above
- the second attempt to start X ends in a machine completely frozen :-(

3) Same as 1) - this time with
Driver "vesa"

Result: Everything works - i.e. back and forth between X and
console. Sure enough working with Vesa is a workaround only given the
huge difference in speed between the Vesa- and radeon drivers.

4) Option "AutoAddDevices" "Off" under 'Section "ServerLayout"'
Driver      "radeonhd"

Result: X works only once (as in Tests 1&2 above). Second attempt to
start X gives a "frozen box" again.

As you already mentioned

o) no problem with VESA-Driver

o) no problems with radeon-driver prior to the Upgrade to X 7.4

Hope this helps someone out there to track things down.
