Comment 16 for bug 57153

Hello everybody, fist sorry if my English is poor but I'm Spanish, well I'm affected with this bug too when I do apt-get dist-upgrade, my hardware is an ATI Radeon Mobile 9700 so I've been using xorg-driver-fglrx with Kubuntu Dapper 6.06.1 I386 and official "dapper" repositories, the bug ocurrs when package "xorg-server (1:1.0.2-0ubuntu9)" is replaced with the new "xorg-server (1:1.0.2-0ubuntu10)", when machine restarts kdm isn't able to fire up any screen/device, I post the error log for people can see I say:
 ----------------------------------------------------------------------------------------
 Kdm Error:(Seen in /var/syslog)
 IO Error in XOpenDisplay
 Display :0 cannot be opened
 Unable to fire up local display :0; disabling
 -----------------------------------------------------------------------------------------
 Xserver Error:(With ati (radeon X.Org) driver)
 .........(End of log)
 (EE) No devices detected
Fatal server error:
 no screens found
 ------------------------------------------------------------------------------------------
 Xserver Error:With propietarie fglrx driver (7.0.0-8.25.18+2.6.15.11-3)
 .........(End of log)
 (EE) No devices detected
Fatal server error:
 no screens found
 ------------------------------------------------------------------------------------------
Conclusion:
 This revision of the package breaks the system, so I raise a question;
 Would be possible to downgrade the package version to the prior wich is in /var/cache/apt/archives in a clean way until the Ubuntu team fix the problem?
Thank's for any answers.
