X take no mouse nor keyboard input

[Zhang Weiwu]

Hello. Can you give some hints what to do to fix this issue?

Notebook computer: Sharp PC-MM2
(I uploaded its photo to
http://en.wikipedia.org/wiki/File:Sharp_PC-MM2_frontal_view.jpg )

Video adapter: Radeon Mobility M6

OS: FreeBSD 8.0-RELEASE

Phenomenon: X server starts fine, where keyboard and mouse events are
ignored (except Ctrl+Alt+F1, which switches away from virtual console).
Both mouse and keyboard are working on the console.

What has been tried:

    * re-generate xorg.conf by X -configure
    * re-start moused
    * reboot
    * try different X clients (tried are xdm and twm)
    * configure xorg.conf to use vesa driver instead of radeon

what happens after these trial:

No change to the above described phenomenon
