Binary package hint: xserver-xorg-video-ati

I am currently testing Kubuntu 10.04 alpha3, and everything works OK except that:
- there is no splash screen and no boot messages on startup (the screen goes blank after making a selection in GRUB and does not turn on again until the graphical KDM screen appears) and
- ** the tty consoles do not work ** (Ctrl-Alt-F1 and the like). There is no adequate response to the Ctrl-Alt-F1 (...F6) keys, i.e. the KDE desktop stays on the screen, the mouse cursor disappears, but nothing further happens. The /sbin/getty processes are running for tty1 to tty6. sudo chvt [1-6] has the same effect. Initially, on Ctrl-Alt-F8 the mouse cursor used to reappear (i.e. switching back to the GUI worked). After the latest updates, trying to switch to a virtual terminal seems to freeze the GUI and, since there is no accessible terminal and a frozen GUI, requires a reboot.

I suspect that the problem has something to do with the framebuffer.

System information: OS: Ubuntu lucid (dev) · Kernel: 2.6.32-16-generic · KDE: 4.4.1 (KDE 4.4.1)
CPU: AMD Turion(tm) Dual-Core Mobile ZM-82 · RAM: 1367392kB/3799764kB
VGA: ATI RS780M/RS780MN [Radeon HD 3200] / ATI Mobility Radeon HD 3400
Installed graphics driver: automatically with OS installation, no modification (must be ati i.e. radeon).
latest updates as of March 17, 21:20 UTC using default sources.list(.d/*) from 10.04 alpha3

What I already did:
1. place Option "DontVTSwitch" "false" in xorg.conf (does not help)
2. uninstall plymouth (does not help)
3. place radeon.modeset in kernel grub line (and remove quiet splash). This makes the boot messages appear and restores the normal function of the virtual terminals. This is a workaround, but: slow graphics, no acceleration, no effects.

The problem does not depend on the desktop/window manager, it appears in KDE/KWin and whatever Gnome uses (compiz or metacity) alike.
