I installed this kernel on my T42p 2373-KUU running a fully up2date FC3
install.

It has the 128MB ATI Mobility T2 chipset.

Here is my report.

When I booted to this kernel, I saw the high resolution frame buffer
activate. All the boot messages scrolled by. So far so good.  However,
when X tried to start to bring up the display manager login, the system
hung.

I powered off and rebooted, and this time booted to runlevel 3 so X
wouldn't start.

As root I ran: /usr/bin/thinkpad-T4x-suspend

My system did suspend OK. I waited a couple minutes then closed the lid
and opened it. My system unsuspended but I could not see anything on the
screen. I was able to blindly press CTL-ALT-DEL to perform a graceful
reboot.

Should I have expected this to work?
