I've got a Pavillion ze4430us, with the same ATI Mobility U1 card, that
FC2 auto-detects and uses the radeon driver with. I have no problems on
any of the latest kernels. I've seen the blanking problem on other
laptops, but have had no trouble with this one. It works just fine for me.
I'd really like the hardware aceleration to work.. but i guess i'll have
to wait on it.

As for the synaptics touch-pad, it was sad that it's not auto-detected,
however, given that the FC2 release date is very close at hand, unless
it's arleady been "fixed", i doubt support will be in the official FC2
release.

I can say however, that setting it up was very easy - just grab the
synaptics driver, unzip, compile, install, and change the driver lines in
your xorg.conf, just like the install file from the driver says. It works
great after that, no problems at all.
