I just updated Debian 6 on my computer and have no mouse pointer since then. Apparently the latest kernel update to 2.6.32.5 reintroduces a bug that has already been resolved. Many Intel VGA chips are affected, mostly on Centrino and Core platform including the i855GM that my laptop have.
root@gxa01:~# uname -a
Linux gxa01 2.6.32-5-686 #1 SMP Tue Mar 8 21:36:00 UTC 2011 i686 GNU/Linux
root@gxa01:~# lspci | grep VGALinux gxa01 2.6.32-5-686 #1 SMP Tue Mar 8 21:36:00 UTC 2011 i686 GNU/Linux
00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)
Temporary resolution is to put the system into suspend/hibernation after which the pointer reappears. One can also upgrade/downgrade the system, as other kernel versions are reported to work. Anyway the best would be the Debian guys to fix the mainline kernel ;)
Update: Solution is here.
