I am getting a blank screen after booting into fedora 12 on a dell insperion,
model pp31L with the Intel Centrino chip. I have to hit the power button to turn off the laptop.

I can boot into centos 5.3 and all is well, but a fresh install on fedora 12,
the screen goes blank less than a minute after booting. I am happy to add info
on the fedora release. I have just installed the fedora 12(final) DVD and
the system in unusable booted to fedora. I can get info by mounting the fedora
partition from centos.

Hardware info:
17" Dell Inspiron with 4GB and dual 250GB drives.
